I want to change rooms. In fact, I want a refund for tonight!
If you tell me the exact problem, I can be more helpful.
Cockroaches have declared war on my room!
Allow me to apologize. I'll give you another room right now, and a full refund for tonight.
Thank you for not asking me to collect the roaches in a jar as evidence.
Sir, only your mother wants to please you more than we do.
