I got mildly excited tonight when the self service machine at Tesco only charged me 95p (instead of £1.99) for a 900g bag of Birdseye field fresh garden peas. I looked round to see if anyone had noticed what just happened. The demoralised attendant at the self service machines was so lost in her world of monotony she didn’t bat an eyelid. I thought about going back to get some more, but thought leaving my cheapo bag of peas unattended at the machine for a short while might have highlight the situation. So I settled for just the one bag at 95p and danced all the way home.
