Strange phone calls asking if we are showing random football games

In the past couple days, I've gotten three phone calls asking if we have a football game on. One was asking about a college football game, the other two about an NFL game. All different people but all with a noticeably long delay in the call connection. They asked about random games that wouldn't even be of interest to anyone in the area. We're more of a small grab and go shop that's been open for a year, have never had a TV and we aren't listed as having one on any sites. We are most certainly not the type of place that would be thought of as going to sit and watch the game. I have been streaming games on my personal device to watch - is this my streaming service trying to find out if I'm broadcasting the game for customers? Or some other entity that tries to enforce these types of rules? Didn't think anything of the first call, but was annoyed/curious by the third.
