Odd key fob not detected issue

Vehicle: 2012 Volt

Has anyone else run into a situation where your key fob stops working at a certain physical location?

There is a local gas station where while I’m on their property the Volt is unable to detect my keys.

It isn’t batteries. I’ve swapped them out. Both pairs do this. The key works fine before stopping there. Once I’m a half block away the “Can’t detect remote” message vanishes. Though I don’t know much much of this distance is due to redetect attempt cooldown.

The only odd thing about the store that I can see is the bank of slot machines right up against the window that’s right up against the parking spots. Which might explain why when I asked the store about it the employee who also has a fob said they never had an issue. Employee parking is around the building with a few brick walls in the way.
