To put this issue to bed:
The bill on Saturday night was settled, and we are all good. UPH paid a table (as he is often so kind to do), and if he hadn't, we would have been short. That really falls on me for not charging everyone the right amount(s) as I am settling up at the end of the night.
I bank on your honesty to pay for how much you play and you bank on my honesty to not overcharge you. This isn't my first rodeo... We may change it up in the future, but I have yet to hear a suggestion that I think would work better than the way I work it now. I am open though.
Thanks again to everyone for coming out. It was a blast!
