Love At The Checkout Counter?

An express-lane cashier looked up and said “How are you two doing today?” Then, immediately, she realized the man and woman next in line were not together. Each had a shopping basket. No one was troubled, of course. But it would have been the perfect moment for the checker to ask, “Did you find everything you were looking for?” The woman in line could have said to the cashier, “Well, apparently I found this guy here — do you have a coupon I can use?”/ Paul Turner , The Slice blog.
