@Laura2592 I had an interesting one a few months back. I have been taking bookings from folks who can pass my "Covid screening" and able to comply with local regulations, such as masking, social distancing etc. And, at that time, there were strict guidelines about people not in one's immediate family gathering indoors. So no visitors.
A guest, flying in, wanted to book with her teenage daughter. But, she said, she wasn't sure whether the daughter would want to stay at my place or with her cousin at a local University (I'm not clear where at the University that was, since campuses were closed at the time.)
She didn't want to pay the nightly additional-guest fee for the daughter in advance, in case the daughter decided to stay with the cousin. She said she'd settle the additional-guest fee by cash or credit card, if the daughter stayed overnight.
But, the daughter might want to "pop in and visit". (not sure if the cousin was going to pop in too)
I mentioned to her that I thought, under the circumstances, that this seemed like risky behavior to me, and that I thought the daughter was better off just planning to stay at my place with mom.
Mom reiterated she wasn't prepared to pay the extra fee if the daughter decided not to stay with me.
I declined the request, indicating that I don't take cash, and don't have the ability to take credit cards, and that I felt it wasn't clear to me that teenagers would take local Covid regulations seriously, and my rules only allow the registered guests to use the space.
I got a really nasty message after that accusing me of trying to price gouge during a pandemic. Dodged one there.
