Hi, Rusty!
I have just realised that it is Thursday, and by now your son is probably with you!
But I shall send this now anyway, whilst I have a few moments......
It has been a tad fraught here, today.
My Tesco store is the reverse of yours!
The ground floor is the shopping area, with some ground floor parking.
The first floor is entirely a car park!
We have a lift and a travellator.
I finally had a reply from the "World of Books" Customer Service Advisor.
He was trying to justify the sending of photographs , but then told me that his manager had intervened, and had said that I was to be fully recompensed forthwith!
I seemingly can expect the money to be in my account within 2 days.
Good for the manager!
I shall offer to return the soiled book (and then they can see its dirty state for themselves) if they provide me with a paid up front "Returns" label!
