Hi, there. Is this perfect English?
The two guys start insulting each other. A bouncer comes over, sensing something is going on.
Bouncer: Is there a problem here?
Guy: No, we're just messing around.
Yes, that's all OK (provided these guys have already been mentioned). Personally I prefer, in careful writing, not to drop optional "that"s (unless multiple instances occur close together). So, I would prefer "sensing that something is going on".
