The reason they turned down the date so easily was due to their attraction to the guy that asked them out wasn't great to begin with. In their minds, they were giving him a opportunity to take them out and give them attention and free shit, not a mutually beneficial desire to vet each other for a long term relationship.

If the man asking was handsome, tall, rich, fit, famous, and charismatic, they would be asking him for the follow up to make sure the date went through. To which they would sleep with him immediately to attempt to lock down the guy they are genuinely attracted to.
