Ah the self checkout staff at our local M&S are a bit special, seems to be just the ones in this store btw
there's one other person using the self checkouts (of 7 iirc).
"Cash or Card?" Card, Use that one there....
But I prefer that one because its card only and there's more room for a trolley as its the end one and I won't get in other peoples way (The cash ones also have the weighing mechanism whereas the card only ones don't - so extra pain in the arse as they are a bit shit)
No please use that one
"Sorry, No, that makes zero sense" proceeds to the one I wanted anyway.
