1 - yeah, nothing wrong with tipping on pretax. And tipping 20% on pretax is better than tipping 15% on the post-tax...doesn't really matter which, a good tip is good and a bad tip is bad. LOL
2 - I WISH I could go!!! I mean, really - a Poker Tournament AT a vaping convention??? That's like an ice cream sundae on top of a birthday cake! It's just bad timing - can't be gone then. The website says there's one in "Northern California" in November. Depending on when and where, maybe I'll be able to go to that one. But I doubt there'll be poker.
