Thankfully this topic died down on my facebook, but for a good couple of weeks I had people posting this stuff constantly and huge arguments breaking out. Which made me naturally curious, do people here tip poorly? Do you guys think you should leave a flat rate or base the tip completely off of performance? A friend of mine has been a waitress for over a decade and she set a few people straight in these facebook discussions and the responses she got made pissed me off. I can't believe some people have the mentality of "If I give you $2, you should be grateful". So, thoughts/opinions?
