I went to Starbucks yesterday. The cafe itself is in quarantine, serving only drivers. I approach the window, stretch the credit card, and to me: the previous customer has already paid for you, said that he wanted to do something pleasant to a casual person. I: Then I pay for the next one in line. I left and think: like I stayed with my own, but pleasantly twice: and coffee on a slice, and did good to another :)
