I do what Miss Dee says. I hate going to sporting events, concerts etc because often the seats are sooooo tiny - at least in comparison with my butt they are. My DH is very slight but has very broad shoulders so he tends to slot a shoulder behind me and I slot a stomach roll over his side! I need my own personal space anyway, so fat or thin I've never allowed physical contact with strangers, but I am even more conscious of it now that I'm larger. I think its just rude to encroach on someone's personal space.
