Actually, those are the only 2 things I will tip on (in everyday life - the same doesn't apply to vacation where I utilize services I normally wouldn't utilize in everyday life). I tip my hair dresser a flat $20 every time. At restaurants, I tip based on service (a flat rate). I never, ever, and will never tip a percentage of my bill. If I have an outstanding waitress who brings my my $10 food she deserves more than a $2 tip and certainly more than the horrible waitress who brought my parties $60 food out and would be expecting a $12 tip. Tipping a percentage "just because" is utterly stupid and cheats the good staff out of deserved tips when its a party of 1 or if its a few people having desserts and the tab isn't very expensive.
