Going out to eat is always fun, but when the check comes it's a different story. I never know how much I'm supposed to tip. Is it 10% of the total meal? If the service was bad, do you still leave a tip out of pity? When I go out to eat, I usually have a standard price I pay, which is $5 no matter if the bill is high or low. Is this too much or is it too little what do you think?
