This still happens in my experience, I've picked up keys from friends and Airbnb hosts via a local business in the past few years.
And over the course of our 6 week stay, we definitely ate at that pizza shop a few times!
Seems strange to me, I've never done anything of the sort and wouldn't consider it. The closest is maybe leaving things at school for another parent to pickup because they left them with my kid.
If the person had a history at denying the keys at random for no good reason, people wouldn't trust them with the keys anymore.
Anyway, it's way more likely that they would call the home owner instead of just denying. People are mostly reasonable.

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.
