You Owe Me
This is a pretty weird exchange, to say the least. The texter, out of nowhere, asked the recipient who they were. After confirming that they were “John,” which is probably a completely fake name, the texter went on about how they were tired of covering “John’s” shifts.
But that’s not all the texter had in mind! They also informed “John” that they still owed them for covering his shifts all of last week! Look, “John” or whoever the intended recipient was supposed to be, make sure you pay all of your debts. Otherwise, people might not be so ready to cover for your laziness.
