Casual Conversation

So weird situation. I'm a contractor that does work at a lot of commercial kitchens. A few days ago I was repairing a piece of equipment at a local resturant where I work fairly often and one of the new employees there called me out by name and said she recognized me from somewhere but couldn't remember where. I didn't recognize her at all. We chatted for a bit while I was working and neither one of us could figure out how she recognized me. I was back a day later to replace a part on something and she said she still couldn't figure it out and of course I still had no clue.

Well, earlier today it suddenly dawned on me. We matched on tinder like 5 years ago. Back then we chatted for a couple weeks but it never really went anywhere beyond casual chatting. I kind of get the feeling that neither of us was in a great head space at the time so things just dropped off.

Well, I'm going back there on Tuesday to finish up the repair. Should I tell her why she recognizes me or would that be inapropriate considering we are both working? The last thing I want is to make someone feel uncomfortable and trapped.
