I tip by the effort expended not as a percentage. If I go to a budget resturant for breakfast say and the Bill is $25.00 and I got a coffee refill and the server wasn't rude I'll leave about 6 dollars.
But if like today we go to brunch at a better resturant and the Bill is $45.00 and I didn't get my coffee without asking twice and the server is rude No way is that guy getting more than the gal in the hash joint. $45.00 plus our tax of 10% brings it to $49.50 so 20% would be $9.90- His other three tables had 4 people each so in one hour his tips would be at $69.30 that is not starving pay by any streach and he just wasn't worth it. I mean it wasn't like he was doing Teppanyaki or anything the jerk didn't even bring me coffee. I left $5 and should have left a penny.
But If we pay by charge we also add odd cents to the tip so that the total bill will come up to the ending number my husband and I have picked for the month that way we can spot a bogus charge on our bill. In the $25.00 dollar example the bill would be $27.50 with tax and we would have made the tip $6.25 so that the bill ended in .75 as that is our number for the month. Since we have started doing this I have caught about 4 bogus charges from resturants a year mostly from when we are on vacation and someone double swipes our card.

Told you I was wierd
