One of the peeves of this job is the frequent return of customers. It bothers me to see someone at my counter just minutes after having taken their money and hear their story. And just now, in between writing these lines, a woman launched into a sad tale about how she was supposed to meet her friend here. And she wasn't here. Damn, that's a human tragedy worthy of a lengthy newspaper article or a special UN commission. Of course, it goes without saying that I couldn't care less.
