I hate going to dinner with big groups of people. Or rather, I hate being in charge of the restaurant plans for eating with a big group. I'm happy to show up and eat and drink, I just don't like being the one to make the reservation. It wouldn't be so bad if your 15 friends were always on time for every get-together, but they never are. So you're forced to stand next to the host at 8:35, the only person from your group who's on time for an 8:30 reservation, and try to convince the guy that the other 14 people in your group are "right around the corner" so that he doesn't give your table away.
