What are you going to do if another couple or two flakes out tonight and not show up? Charge extra to the guests who show up to recover the costs?
Jesus, this reminds me of something that happened to me years ago.
I went to a friends house, where she'd invited 4 other gals over to watch movies and eat pizza, so 6 of us.
Pizza arrives, cost with tip let's say was $30 for 3 pizzas so should be simple enough to figure out 5 bucks apiece.
I remember tossing my $5 in, and tried to concentrate, unsuccessfully on the movie, while there was all this discussion, wheeling and dealing, and general confusion over who should pay how much. It went on forever, like 20-30 minutes, while the movie was going along.
Finally, giving up on watching the movie, I finally paid attention to this financial conundrum, and saw that for some ******* reason, there was only some odd number like $21.00 in the pile, and no one could figure out, or own up to the fact that 6 x 5 = 30.
By this time, the pizza was gone, I'd gotten 1 lousy slice out of it (it was really nasty pizza too), and by the mere fact that I was the only one that hadn't engaged in this complicated conversation, I was getting the fish eye.
Long story, realizing this was going to go on the rest of the night, I threw another $10 into the pile. So I got one slice for $15, was still hungry, but everyone finally shut up about it.
Then the conversation started again with "What's going on in the movie, I didn't see any of it"
