I was in the check-out line of a local store yesterday. A man was buying a jar of pretzels, simple enough, but he presented clerk a coupon and a couple of other vouchers that entitled him to some discount on the jar of pretzels. The transaction must have taken at least five minutes. This happens so often at the grocery store, where someone presents a handful of coupons that the checker has to enter into the system one-by-one. I am sometimes tempted to ask these coupon clippers for my share of the savings, since the waste of my time enabled them to save money.
