Oh, I online shop - but I'm with sweetpeach, they will give you stuff that's closer to the expiration date and that's annoying. Usually the guy from Sainsbury's lets me know, so we can plan our meals accordingly, but still.
But yeah, we went to Asda the other weekend and it made me so irate. Getting slammed into with carts, no general courtesy when trying to get down the aisles, etc. It can be the same in the US in our larger Stop & Shops, but doesn't make it less annoying!
