I'm a 99%'er, and he was obviously a 1%'er. So, it had to be true!
Actually, that's a pretty good tip -- about what I usually leave for good service. I don't bother to calculate 15% -- I just double the amount and move the decimal point to the left by one digit.
I also round to an even dollar -- it makes it much to compute the total.....
Just like me.
Although he tips more.
