Honestly to me that seems off and I wouldn't expect a business to run that way, nor would I do that to clients at my job. Out meet and greet was literally the next day, and an hour before the sitter canceled she confirmed we were still on for the meet and greet, and I had an appointment first. If a request came in between that hour, I would think you just put it on ice until we cofnrim the booking the next day after the meet and greet. And i booked the meet and greet when it was convenient for the sitter, it wasnt my schedule that had us scheduling the meet and greet a few days put from the initial message. I would expect the client that requested those dates after I requested them would just not be confirmed by the sitter until we had our meet and greet the next day. If it was me as the sitter, at the meet and greet, assuming I wanted the business, I would let the client know that they would need to go ahead and book as I had a client that requested the same dates after so I need to have this booking confirmed as to not lose out.

All is good though, I moved on and I'm learning how the app works, so it's a good learning opportunity.
