Steve hated this part of being a landlord - chasing tenants who refused to pay their rent. Collaring Eric wasn't too difficult; he was a creature of habit and not too bright.

Steve changed the plan and invited the couple around for dinner with him and his wife. Eric now had the means to pay his rent - Lisa!
