In the last ten to fifteen years, there have been several members of my family or other young adults I know who were or are waitresses or waiters. Every week, they will argue amongst themselves about who has to work the shift from noon Sunday until close. The reason is that groups of customers who come into restaurants after church are the rudest, most arrogant, demanding, and cheapest tippers among the general population either on that day or any other day. At first, I thought it was an exageration, but after hearing it from several people, and seeing it myself quite a few times, it is a real phenomenon. Although a fact, I am at a loss as to understand why. One would think it would be just the opposite, especially in light of being a witness wherever we go. Does anyone have any explanation, or have you experienced this? What waiters do to the food of those who act like this is the subject of another thread.
