It's pretty flawless, yet oh so simple. They are so often mocked and shamed for eatin  1000  g ANYTHING in public (as they should be) that when they eat an ungodly amount of junk food and someone who appears very sweet and genuine turns it into an experience deserving of pride, making them think they impacted your day.... well, they become overjoyed.  I do everything I can to make my customers overjoyed. I joke with them, tease them or myself if they have the right kind of humour, help them find things if they're visiting, tell or listen to stories, and dress as nice as I can and always smile. I do it, usually, because if I can be happy at my job, and have happy customers, I can have a great day and make good money too. But some people, like rude bitchy customers or demanding people or, of course, fatasses.... I do it purely for tips and don't care if they are otherwise satisfied or not. I just go chameleon and become whoever I think they will warm up to the best during those short encounters I have with them. I don't like to be manipulative, but I am very good at it when I need to be. When I am trying to make a living on dimes, I need to be. I'm just happy I can remain genuine with the other 90% of the people I serve because so many of them are genuinely sweet, funny, kind people. Fats are just part of the job, I guess, like any other.
