Wombling.

I went to Tescos today to do a "big shop"....and to collect some club card points that Tel didnt claim when he shopped there before Christmas. The lady at the customer service desk said she couldnt give me the points as the receipt was over 14 days old...and they had new rules in place now due to "wombling".
"Wombling" is when people pick up receipts from trolleys or bins around the store, and claim the clubcard points for themselves.
Oh dear.
