this disturbing culture..

Something about the new world culture of burping at will really bothers me these days. Anywhere I go, whether it's in the States or overseas, I find people who don't bat an eye after burping. I'm not only talking about small burps either, in group meetings during the last school year one of the girls would frequently burp loudly, then carry on. Perhaps I place too much emphasis on refinement, but this is something that really disturbs me. The worst kind is when someone burps in the office, the smell slowly wafts through the air, and you're stuck wondering how to not throw up and still smile. When did it become socially acceptable to do this? Or am I really looking for bones in a chicken's egg? (To use an old Chinese saying.) Your thoughts?
