On my way home from work, in uniform, I stopped at Sainsburys under instructions from the glamorous Mrs cpunk to buy some wine. Whilst going through the self-service checkout, I was approached by one of the staff who asked if I was 'on duty'. I said no and his response was 'Oh, that's OK then; it's just we're not allowed to sell alcohol to people who are on duty'. I thought this was a bit odd; and as I think about it more, it strikes me as even odder. What the fcuking fcuk business is it of theirs whether I'm on duty or not, and what would he have done if I'd said yes? To be fair to Sainsbury's, he didn't seem the brightest of individuals so he may have been barking up some tree of his own invention, but it would take an imaginative leap to do so. Any thoughts or similar experiences?
