Boots Chemist in the UK often print coupons at the checkout, and more than once I have been handed coupons for hair care products. Normally I just say thanks and bin them later, but on one occasion after being handed such a coupon I said to the cashier (with a big smile on my face) - "Are you sure about this?".
Finally, she actually looked at me more closely, laughed out loud, and said perhaps I could give it to someone else. All done in good spirit i hasten to add........
