Yes, my common sense tells what is appropriate and what isn't in public. You have to keep in mind that every single person has something that they are sensitive about and they usually have a legitimate reason for that. Thew problem is a lot of people don't have a filter between their brain and their mouth. They just say whatever is on their mind without thinking. And this is what can happen when you do that. I basically don't say anything in public that could be offensive to people in general but yes I also take the crowd i'm with into consideration as well, like with your situation.
And of course, before anyone says it.... Its not about being "PC" its about not being a douchebag.
Its simple: When you are in public learn to think before you speak. Its really not that difficult. I have enough sense not just blurt out things that could offend others when I am in public so I don't have these problems.
