Hey - no need to apologise
I understand what you're saying and the staff have spoken to him about it, so hopefully he'll take it on board. Considering the recent bannings we have had to make, the staff have been keeping a closer eye on all involved to make sure that it doesn't get all out of hand but if you happen to come across anything you feel is not right, simply report it and someone will look into it for you.
Never worry about saying this sort of thing - we're here to help and unless someone tells us they have a problem, we won't know
