You're right.They would have called him in in private and told him to leave without saying any goodbyes.
If Russell Brand had still been doing BBLB he would have giggled something about there being a case of 'really bad sexual assault, and no mistake' like he did with that dopey girl who used the n-word.
That was bad, and she should have gone, but I don't think there was any serious intent to racially offend people. Just a stupid girl trying to be hip.
Coleen is so desperate to please she probably truly wasn't offended. And if it had happened to someone else she'd have probably said she was making a fuss and that Harvey didn't mean it.
I can't remember now what the reaction of the other Hamsters was. When Harvey was discussing it the next day they seemed reluctant to comment. Were they surprised or shocked? At least they didn't join in. God, that would have been really bad.
