A: I'm in 507. I have a few problems with my room.
B: What is that problem, sir?
A: There are cockroaches in my room.
B: Are you sure, sir? Flies I could believe, but cockroaches?
A: I've counted nine different cockroaches, and I accidentally stepped on another one.
B: Sir, we run a spotless and cockroach-less hotel.
A: You dare to doubt me?
B: I'm sorry, sir. Let me transfer you to my supervisor.
