I guess I'm in the minority, but a little BO doesn't bother me. A little. If someone doesn't wear deodorant for a day, I don't care. I'll notice a smell, but I won't necessarily mind. If it's a period-related smell, that will bother me. If it's someone who smells as though they haven't washed in more than a day (as it may be in this case), that will bother me. When people don't wash for a loong time, the smell literally stings my nose.
