When we were visiting the UK for my Mothers 90th birthday we went to the local Morrisons for all the party stuff.
I was with my DD and her then partner(French speaking).
We got to the check out and I was asked if I was over 25, duh, just a wee bit.
I was then aske dfor ID, come on, really i said.
By now DD and partener were in stitches, speaking French of course.
I handed over my Belgian ID card, and she said she could not understand it and did not then accept it.
I asked to speak to a supervisor, one duly came I showed her the card and she could see it was in French and ENGLISH.
We got our wine and beer but DD still has a laugh about it, it would be funny if it were not rather sad and silly.
