i am an 'extreme tipper' when i eat out,, there is this one,, that no matter the time of day,, we get this one waitress who will knowingly serve you cold coffee,, so we leave if we get seated in her area. and everytime we get seated in someone elses area we get great service and hot coffee,, and they get a very good tip. i have talked to the mgr about this,, but he doesnt really care. the only reason i eat there every now and then is because the cook does a really good job on 2 items i want to eat.
