Casa what happens if you kick the door in holding a decent sized kitchen cutlery knife with some dead animal pieces still on it and The Crazy in your eyes, asking who needs to die first?
Only half-joking. I took a similar tack with parking issues and now, no problems. I have had enough landlords with "live in property managers" aka their alcoholic asshole buddies who invariably start bilking the rent, then ghost, and the locks get changed, and us tenants get extorted by the landlord because we need our clothes/sleep/running water to be presentable employees. The police tell me to go to court, get a judge to say I was wrongfully locked out, then they'll open the door for me.
That shady sh!t goes both ways. Almost every one of these people complains that I put "January Rent" in the check's memo. You try and try to be cordial, but eventually, you need the threat of psycho Hannibal Lecter sacrificial art installation graphic murder to keep the shitheels in line.
Nobody cares their fire pit is flooding your apartment with smoke until, instead of closing your windows to the smoke, you just leave with the smoke alarm going haywire, they half-heartedly apologize like you're going to close your windows, and you just say oh it's no worries I won't be around to hear it, have a good one! They don't want the fire dept citing them for the fire pit.
I like several of the suggestions.
1. Blow the cash/card, then tell the guy you considered that a payment on his existing tab and he has no credit/deposit.
2. Return the cards and be honest about it
