Your original note asked if you should be compensated for non-disclosure of the fee. My experience is that they credit you for the full cost of a night's stay if you are less than 100% satisfied. You slept in a bed. You had indoor plumbing with hot AND cold running water. Your door locked. Do they owe you a free night's stay because someone didn't tell you about a $1 fee?

Your second note comments on the clerk's attitude and implies that that was what reduced your satisfaction. While I can understand him laughing about this, he is in a customer service role and should remain professional. If his behavior was inappropriate then certainly it should have been / be raised to management.
