When paying a bill there are all different personalities and issues. Some watch their bill
very carefully as they are living day to day, some watch it closely as they were raised to
be very suspect of the one billing, some are just plain cheap and get a kick out of stiffing the business or help, some are just paranoid and think the world is against them and trying to cheat them, etc etc. It is my belief that when they enter a restaurant they have some knowledge about the place, what it charges and conclude they can afford it and if not they should not go in in the first place. Once they are charged and have eaten their meal then for God's sake pay for it. If you don't like the service, don't like the food, don't like their practices then don't go back. But to try to impact their business with worthless complaints is abusive. To stiff or leave a low tip is a real bottom feeder as
those person's are relying on that income to feed their families. If the service is below
a standard you have no idea as to why so you take it out on the most vulnerable, the server who may be as frustrated as you are!
