You don’t have to sit next to them or smell them. Lol I’m kidding and see your point but people need dress decently and be respectful of others.
True .... there’s always someone who has to make a statement that really is offensive. When I flew Frontier (as a pilot) we had a few folks who did wear offensive clothing and I just told them to go to the lav and turn the t-shirt inside out, or, just get off my plane. One wore a military t-shirt and some Karen got her knickers in a twist over it and I told her either shut up and sit down or I’ll throw her off MY plane. I get a standing-oh over that.
