It’s really rude and disrespectful to just assume it is OK for them to have a package delivered without even asking you. For reasons too obvious to enumerate!!! What if it is contraband!!! YOU, the addressee, will be held responsible! The potential consequences of accepting mail by unknown persons (let’s face it, AirBnB guests are basically unknown persons) are far worse than a deluge of catalogs arriving. It’s hardly a petty thing. I’ve had guests ask me to receive their packages, (one just wanted to send new contact lenses here) and I’ve always had to decline. Fortunately, we’re on a rural route that doesn’t get mail delivered to the house which makes my denial easy.
Frankly this whole situation sounds dodgy. I would leave this guest a negative review. Just that he’s been so weird about the reservation, had something unknown delivered to your house without permission and then wanted the cousin come in to (probably) get his package of drugs is all weird.
Robert, as an English major, I don’t understand your reference to Lady Macbeth’s sleepwalking scene, where she incriminates herself in the murder conspiracy with the famous “out damn’d spot, hell is murky” line. How is that relevant to this question? Or are you still obsessing about your own damn’d gasoline spot that won’t come out no matter how much you wash it? At least there is not murder involved. That we know of. LOL.
