I see the fedoras are out in force. -.- It's kind of dishonest to say "no". Don't get me wrong, I'm sure most guys wouldn't come out and say something blatant. But ultimately there's no hard and fast rule for what someone might find offensive. I've been reported for sexual harassment for trying to discretely inform a co-worker that her pants were unzipped. You might think whatever you're saying is fine, but the other person may not agree.
