I think I know the absolute worst way to treat a customer now. I went to a food chain (that will remain nameless) and the lady taking my order just acted put out by the fact that I was interrupting her ‘doing nothing’ time. If I am interrupting you so much, just get someone else to take my order, do not try and make me feel guilty because you have to work. We have all encountered this scenario sometime in our lives, and we all hate it. It is very frustrating to have someone act put out with you just because they are working and you are not.
