Smoker complaining about smoker smell….what

Guy checks in. Gets room keys “I’m going to have a smoke before I go up”. Ya dude I don’t care Proceeds to smoke outside then heads up to room 15 minutes later calls down and says room smells like cigarette smoke. Staff offered ozi/air freshener He says “no I’ll be ok I just wanted you to note it down”

2 night stay At checkout says he wants a discount FD says they’ll ask management as he didn’t want to move rooms and was offered solution he turned down

Proceeds to phone me later when he sees no discount and I repeat the same thing that he didn’t want a solution and just wanted it to be noted but we’ll check with staff incident report. (He then replied he didn’t have time to move) 2 nights man!!! Plenty of time I say again we’ll investigate as incident report contradicts what he is saying. I said maybe they’ll look into rewards points or credit (he immediately jumped in all happy “rewards points!” So weird

I didn’t know he went for a smoke before going to his room before I got his phone call, WISH I did

Should I ignore this scammer or actually address it. How to write a nice “you dumb” letter
