I had booked a weekend away with a small group of friends. I am the only single woman so I booked a twin room for myself. Booked a twin so it was easier if it came up that someone wanted to share.
That has happened, a friend of a friend will be coming and sharing with me. I don't know her well but she's perfectly nice, it's only 2 days and we won't actually have much time in the room, it will be fine.
The room is already booked and paid for, I don't need the cash, had expected to spend the full sum. She has offered to drive which, even with the increased cost of petrol will amount to much less than the room, but I'm am perfectly happy to say the room's already paid for, lovely that you've offered to drive let's call that quits.
Is that OK or in her shoes would you prefer to divide everything equally? I always feel a bit uncomfortable offering/calculating petrol money. For short trips with friends we generally buy a cuppa or something but this is 150 miles.
