I didn't even bring my phone. I did bring beer, and even shared one. They close the meeting, I'd go sit at a machine and play black jack. Along comes a nice woman offering free drinks, I say "Sam Adams" every time. When the meeting reopens, I'm set!
I think I lost around $100 total gambling (up at times, down others), but I guarantee I got more than my money's worth in beer, especially if you figure at bar prices! Shit at a dollar a beer, I'd have at minimum broken even. There were a couple of times when I'd get into a conversation, and think 'wow, my tongue feels thick!'
