Your last should have the option of NONE AT ALL THE MADNESS MUST STOP. Sorry baristas out there but what is next, tipping the person who makes your McDonald's burger? Note for the soft touches among us: just because there is a tip jar doesn't mean you have to put anything in it.
Otherwise, the appropriate amount to tip depends on local mores, so your poll may not be a great guide unless we say where we're from. ^^; In Montreal waiters are taxed under the assumption that they're tipped 10%, which has edged the usual tip upward to 15% of the post-tax bill. In Toronto the usual tip is 15%-20% of the pre-tax bill (in Canada the difference is sizeable). My hairdresser gets exactly 20%. Taxi drivers get an amount close to 10% most easily handed over without resorting to small change, which would probably annoy the guy more than anything else.
