Is it just Morrison’s that have a separate basket queue

[Mostpeculiar]

Can’t be arsed to stand in a trolley queue

Depends on the supermarket. Some do. Some don't. Even within the same chain it varies.
That's a 'how long is a piece of string' question.
Sorry that's not much help but - hey that's life.

No problem Morrison it is

I have only seen it at Morrisons
