Why not do the best job you can all the time?

I'm sure there are food outlets in your area who would like to hire wait staff with a will to succeed regardless of the customer's attitude and behaviour.

Better establishments might equal better pay and even some support from the company that's not been fought for by unions and lawyers; just common decency to the people who are the face of their business.

I may be imagining a utopian ideal there, but it never hurts to encourage someone, which was my intention in this post.
