Promotions dos and don't.
Do not argue or get into any type of debate with customers, clients and managers. Even when you know you are right. Having any dispute with any of them can lead to you being blacklisted with that company. In the marketing world, everyone is right except for you. It may be harsh, but it is the truth. Live it, breath it, and Suck it up. If you can do all three, the benefits will be more money in your pocket. For that promotion in particular and future events. Customers can act like a true female dog. When it comes to free stuff, they will attack you like have 100 dollar bills taped all over your body. Trust. Its even worse when you give out something good and rare. Example may be food, anything eatable, and clothes. Be mindful they will beg like puppies for one two or three more samples. The stories you will usually hear are, can I get another on for my child, my wife is right there, can I get one for her, can I get some for my co workers, and anything else similar. Even if the client or manager says give one per person, if they are not in eye sight, give the potential customer what they want. Take a quick look around before you do so. You don't want to get caught and get a warning from the manager.
Believe me, the customer will be happy and so will you. The quicker you give out the samples, the quicker you will be done. Depending on the manager, you may also go home earlier and may get a full days pay. Maybe. Depending on the manager of the event, which I will get into later. If the manager is in eye sight, just politely say, I'm only allowed to give one per person, my boss is watching, I may get in trouble. Most people will understand and be on their way. But you will ruin into a few that will watch your manager and say, he's not looking, pass me another one. If that is the case, glance and pass them one. These type of people will stay next to you all day, or may even snatch a sample out of your hand. If this happens, which is rare, or any altercation, brush it off, take a walk if you have to or even tell your manager. Letting the manager know will relieve some of the distress you have. Never get into an argument with a customer. That one argument can cost you your check, and future work with that company. Believe me, you don't want anyone to mess with you check, bad enough you may have to wait 6 weeks for it. If a situation happens and you know you are about to fight, take off your promo shirt, and anything branded you were given before doing anything. Every party involved in the marketing event will tie the situation to the brand you are promoting. For example, if you get into a fist fight and was promoting Sirius Radio, customers, and the media will believe Sirius radio employees fight in the street. Customers, Sponsors and other personals of Sirius radio will have to spend more money on public relations to get rid of the bad publicity. There efforts when from promoting the product to promoting and gaining their "Good Image" and behavior. During this process, sponsors and other firms who partner with Sirius radio will take their money and run, causing Sirius radio to loose their profits. Think what baseball players do when they get caught doing steroids, or other inappropriate behavior, they hold press conferences, higher lawyers and public relations staff to clear their name. That cost thousands of dollars that clients don't want to do. So if you are involved in a bad situation that seems to get worse, take off the brand name. It will cost future work with that company.
Arguments with the managers. Because they are in charge of the event and the staffing agent hired them, this can make or break working with that company. People will abuse their power. If the manager really remembers you after an argue, and you were hired for the same event, they can call the staffing agent and get you replaced. The manager can make a convincing argument saying you are too difficult to deal with. This is why arguing with the manager can cost future work. I have personally spoken with managers that say they have done this in the past. If there is a problem, or disagreement, call the staffing agent and let them know the situation. Try and be calm and polite about it. Let the agent know the manager is being difficult and you don't fell comfortable working with them. The agent may ask you to stay and make a note not to schedule you with that manger in the future, or ask if you want to leave, and get paid for the hours you have worked.
Overall, when you are working a promotion, try to avoid any altercation with anyone that has authority over your job. When people get mad, they will over exaggerate the story, and use their authority to get rid of you. Yes, you may not care at the time, but when you are looking for promotional work, you will regret what you did.
