Last night we are eating at an expensive ($300/2 people - only 1 drink each), well-known restaurant, when, about 1/2 way through our omekase, a man is seated at the adjacent table. He appears reasonably well-groomed, is part of a gregarious table of 5, and seems to be a regular (we are not). Within a few minutes, it becomes obvious that he don't smell too good. Nobody else notices, but we are closest (other than his own group and the wait staff).

We basically just sat there and took it (actually, my wife moved the candle to the other side of the table). Any experiences like this? Any recourse? Creative answers appreciated.
