is a LOT different than saying "we're a bit unique in that drinking alcohol on campus is against the rules". The way you said it makes it sound like the act of taking a drink anywhere around us is going to be offensive. Just saying.
And personally? I'd prefer to have new good people around who failed to realize a rule was in place and drank in the stadium. But that's just me. Now they know so I assume they won't do that, but anyway - we're good! Sounds like we both are getting at the same thing 👍🏻
