I used to work in a Casino.Now I am working in a promotion booth.Our lines are so long at times and to keep people happy,I always do stuff to make them laugh.One time there was a short line and I went over and told everyone,“If you are over 21 please leave.” The people who knew me laughed but the ones who didn't kept looking around.One even tried to leave but they told him I was kidding.There were two young girls signing up for a player’s card.I told them that I was wanted in 54 states.They looked at each other and one of them told the other that she thought there were 50 states.People just made me laugh when they looked confused.There were times that I would entertain the people I was waiting on and I told them that after I was finished with them,there would be a $10 entertainment fee.Most people would just laugh,but there were some that would look puzzled then go for their wallets.I just told them I was kidding and all laughed.There are so many things that I can do to make people laugh while I am working.You just have to be there to get the full experience though.
