Is this a lot more than in the US?

Because that liquor servers minimum wage works out at £5.53 an hour. Minimum wage in the UK will very shortly be going up to £6.08 an hour. This is what bar workers here will recieve and very few will get tips.

Seems a bit much that bar workers in Canada expect a dollar or two each time you buy a drink when their wages aren't actually that bad (though of course, by no means generous).

I expect most of them end up earning more than I do for a degree level job...
