Did this the other day at one of my jobs. In my year off before going to med school I am working as a bartender for a catering company. I make sure to only sign up for events where I am serving drinks and not working as a server clearing people's dirty dishes. Well, last weekend, of the managers at the event I was working at comes up to me in the middle of the event and says, we want you to serve, we want to switch you out with a female bartender. Now, I am always willing to help out as I help with the setup which involves carrying boxes, ice, and throwing away trash at the end. However, call it elitist or whatnot, but I do not feel right taking dirty dishes from the table of millionaires at these events (I saw donald trump there the other day) knowing my hard work in college and the disrespect I feel from being "the help." So, I looked at my manager and said, "I only sign up at events where I am promised beforehand to be a bartender, I do not serve." He starts arguing, and while mantaining eye contact, I tell him "I'm sorry, but I will not do it." On a side note these were some the rudest managers I have seen in my life. Right after my episode, I was consolling a female sever who was crying because of the treatment from guests and the managers. These companies prey on people who cannot afford to lose their jobs and for that time being can treat their staff any way they want. If I ever don't feel like studying in med school, I will draw inspiration from these experiences of the 'real world'
