So I was queuing at my local Morrisons, waiting to get called forward to the checkout. I happened to look up, to see that the aisle that the queue was in had the sign Stationary. I wasn't moving at the time, but there were envelopes on the shelves.
They have just had a reorganisation in the store and moved everything around, so the sign will be new.
I didn't mention it in store as I didn't think they would care but I did sigh inwardly.
