Sorry I took so long coming back to this.
We had 8 people there this year. It was fun. I even got a call into TonyV to say "Hi!".
Ohioknight. I wouldn't worry too much.
While there were separate checks for everyone, I had the server keep a running total for everyone and he got an extra tip from me based on that. I do it every year, because it keeps the servers happy (the one at GenCon from just before the closure announcement was a whopper and they couldn't believe I was actually tipping that much).
And Nojiyat, just figure that so long as I'm attending GenCon and Origins (as I'm a vendor and a sponsor, that's pretty much a given), I'll be doing a M&G. So I hope to see you next year!
