Also, just thinking this through.
If she only came back in the taxi with him, to be lent cash/have her taxi paid for .... Would t they have told the taxi driver that and prepared them for continuing on the journey to her home??
The obvious thing to do would be for her to stay in the taco, him to grab the cash, pay the driver for both journeys or for his, and give her the cash for hers. Why would she even get out of the taxi and go into your home?
The totally obvious thing you'd ask the tact driver when you got in would be could be continue on to get place after stopping at your for cash.
In the vast majority of cases the taxi driver would accept that and take the second fare, rather than have to go from a drop off to a new pick up, and waste time getting there for another fare. He already had another fare in his raci, no travel to pick up necessary.
The story doesn't make any sense
It would only be if the driver point blank refused to continue on with her, which seems unlikely.
Even then, coming in to order a new racy and wait didn't need to end in shagging.
But I think they went home, your home, together, intending that from the start.
I'm sure she had other options to get home.
