This is David Manning in Room 417
I checked in about an hour ago,
and it's much too warm in my room.
I tried ajusting the air-conditioning,but it doesn't seem to be working.
I'm very sorry , Mr. Manning,if you like , I can move you to a different room.There is one down a hall from you that's being cleaned right now
so it should be ready in a few minutes.Thanks, that'd be great.Should I come down to the front desk?That's OK. Just wait there and I'll be up in the moment with your new key

What problem does the man report?
His room has not been cleaned.
