It's 2am on a Saturday morning and I fancy a bottle of Cab Sauv.
MASSIVE 24 hour ASDA - one person on one of about 100 tills, fair enough, it's late, the staff are knackered and there are probably about 50 Asian corner shop owners and their kids dotted about the place ...and me with my bottle of wine...
Beep "Approval needed" ..scans around, no one there, takes a seat on the nearest flat surface to await attention "Unexpected item in the bagging area"
YES ...ME, getting bored and impatient!!!
