We do it everytime we eat anywhere.
Ate at Rathbuns Steak in Atlanta after Georgia game (awesome place for steak in Atlanta area if your ever in Atl looking for a good steak)
Generally it evens out on smaller tabs but last three times we have ate with larger tabs the same guys card has been drawn. Do you ever feel bad for the guy and maybe give him some money even though he lost? Same guy got stuck with a $700 plus check for dinner tonight and had one almost $1k not too long ago. I didnt give him anything and actually found it hilarious but was just curious if any other groups did this.
