Well, I'm pretty sure I wouldn't but the idea that a local store owner wouldn't give me if I were to give off a "dangerous vibe" would be somewhat concerning. But maybe I have ancestry etc. where I just don't give off that vibe. More generally, I guess I'm just pretty used to lodging where a delayed flight doesn't mean I can't get in.
I'm a paying customer, why tf should I care what the clerk thinks?
I paid the money, give me the key. Plus at no point did I pay them any money -- they're just, essentially, key escrow.
It's good marketing for them since being in and out of a pizza place means someone will likely buy a slice, but as a BnB customer IDGAF what they think outside of giving me that bloody key.
