Thinking about it, when I do play live, I always leave the table and go eat somewhere (if I'm playing cash). The room I would usually go to wasn't super busy, so I could leave my chips at the table, go eat, and come back and get back in the game. And for tournaments I would eat before hand, and grab something at the break. Everything is close by.
But I just think about how
dirty those dang chips are, and if it's finger food, I'm putting that in my mouth? No thanks. Plus then, it feels incredibly rude to be smacking away at something, potentially getting my food on the chips/table/etc. Now mind you, I've never played a marathon grind tournament like a
wsop tournament, or some of the bigger Vegas style tournaments, so I might change my mind then.
