Short handed question (maybe dumb)

[NotMitch]

I jumped into a 3 handed game in Tahoe last night to make it 4 handed, soon after one guy left and it was back down to 3, and we played for about 2 hours. Three handed this game was awesome in terms of having fun and EV. After a while I wanted to get up and go to the restroom but I was worried the game would break. As it turned out the game broke shortly after so it wasnt an issue, but if you are playing 3 handed or so how do you handle bathroom breaks?
