@Linkat,
I just clicked on the link again linkat, seems to work for me.
Just curious, do you really know people here in the States that are so cheap they tip next to nothing?
I mean, I believe you, but I can't fathom not leaving at least 15%. At least I've never eaten with someone where the amount (thereabouts) got left.
That is definately one of those things that if you're not prepared to leave a decent tip, don't go out.
Re bad tippers, I bet you can pick them out by the bad haircuts they must have for stiffing their barber or stylist the time before their current cut.
I live by the creed that if someone is standing over you with scissors, razors and chemicals, and has the power to make you look awful, don't cross them.
Think of what a difference a decent tip would have made in this persons life.
