<human>: Could you distill the essence of the text into 1-3 sentences?

After two years of waiting tables and now a year out of the service industry I have had this conversation with MANY friends and coworkers alike. I seem to get the same answer. 

Working in the service industry (waiting, pizza delivery, ect.) absolutely makes you racist. You rely on the kindness of others for your general welfare. If they don't tip you they are taking money out of your pocket because THAT group of nice looking people would def have tipped me if you weren't taking my table space! 

Sad but stereo typing happens and then it becomes self fulfilling prophecy by my service level wanting to fall in anticipation of the shit tip I am about it get. Just my experience and friends from around the country agree. Your thoughts? I started this post after noticing how high up the pizza delivery story got.
<bot>: Waiting tables made me racist about certain things. Wish it was different but it is what happens when your income is reliant of others.
