My girlfriend of almost 4 years would not be pleased if she knew how much I have spent on poker related things, but each time I have a different set of chips out, she doesn't even notice they have changed.
I made her play me heads up with TR King Casbah Clubs, then a month or two later we played again and I had Pharaoh's and she didn't even notice!! Now I just showed her my custom ASMS, and she just looks at them and walks away!!
I have a funny story when we were playing heads up once, she made a J-high straight on the turn, which also made me a small flush. She knows very little about poker, but I taught her how to slowplay, which she did, the she went all in on the river (very proud of herself with the straight), I called, and we have not played poker together since (we're both VERY competitive).
She's never thrown my chips off the wall, though!!
