My 9 y.o. scored a beautiful goal in hockey so he won this "sports clip - coupon" for a haircut.
We arrive there and after a 20 minutes wait my son goes proudly with his coupon and they ask for his ID (I repeat, he's 9)
I explain that we don't normally carry his ID but we can provide any piece of ID that we, as his parents, have. They refuse to accept the coupon and offer us the possibility to pay for the cut instead. My son was very disappointed but at least he learned about fake advertising.
