Update: She Came Back… Again?

So, I try to take one day off a week to relax, see friends and family, spend time with the dogs, and catch up on a little bookkeeping. The day after my day off, I came in, and one of my employees mentioned, “Some lady came in with a full loyalty card, but I told her what the policy is and when we stopped accepting them.”

Curious, I asked what she looked like, and the description sounded very similar to the woman who tried this before. I asked what she said when told no, and apparently, her response was… “It’s just one coffee.”

Now, here’s where it gets interesting—this employee wasn’t even working the day the original woman came in to try and get a free coffee from me. So, if it was the same person, it means she deliberately came back on a day I wasn’t there to try her luck again. And if it wasn’t the same woman, what are the chances that two people, matching the same description, with fully stamped old loyalty cards (with stamps from over 10 months ago), both tried to pull the same stunt?

Now, I’m not saying she’s running a long-con coffee heist, but if she comes back in wearing a fake mustache and glasses, I might just lose it. At this point, I half expect her to start recruiting backup, like some kind of underground loyalty card syndicate. If she puts this much effort into a free coffee, imagine what she could do with a proper hobby!
