Ah. I was thinking liquor store, but yeah, I totally get it. Pretty much the same thing.
Me and my cousin bought a liquor-convenience store from a seemingly nice guy who'd immigrated from Syria, and we allowed one of his employees, his cousin "Jim" to stay on til we got things arranged the way we wanted (to where it made sense), and one morning I see a customer walk out without the newspaper he'd just been charged for, so I called out, "'Scuse me, sir, you forgot your paper!" He said he didn't buy a paper, and Jim looked at me with a weird expression. Like he was scared or something.
Apparently, after making coffee, it was Jim's job to replaced that newspaper with a new issue every day, including his last, and he always left it lying there on the counter, unopened. People had little choice but to set their purchases down on it, he'd ring them up and bag their stuff, and the customer paid the total, which included $2.00 for the newspaper ($2.75 on Sunday), and left. Without the paper.
That happened over 100 times a day.
Needless to say, Jim was fired that very morning and left without his usual "bonus". I didn't even let him take his coffee. In fact, he didn't come back for his final check. But I didn't write it anyway, so that worked out.
