Ask any server and they will tell you how deflating their job can be. If they are industrious, they wait on people’s every whim in hopes of adding a few dollars in tips to their less than minimum wage salary. On a bad day, they would have made more money working at a fast food restaurant. Truly good days are often few and far between.
Thankfully, I have never had to wait tables, but my friends who have, tell me stories of the unbelievable rudeness and self-centeredness of many restaurant patrons. Perhaps an even larger insult is that to the majority of restaurant patrons, the worker is a nameless, faceless blob with food.
