Agreed. I was responding specifically to those posts were rounding their total charge to the dollar. For instance, your bill is 33.21. 20% is ~$6.60. A lot of people will round that up to $7. But some people, including me, will occasionally round that to $6.79 to make their total charge $40.00.
It would be an interesting stat to see how many people in this situation would tip 6.60 and how many $6 or $7.
