It all depends on where i am. Take grannies for example...around one of my grannies, i could let off a stream of expletives that would make a whore blush and she wouldn't bat an eyelid. In fact, she would probably join in. Another granny in the same situation would frown upon my use of language unless i was quoting someone else or using it to make a point. Third granny (i have three, long story) would probably keel over on the spot. It depends on the company i'm in, and if i'm unsure as to what language is acceptable in any given company, i just don't swear unless i hear them doing it first.
