I'm biased but in an instance where the only evidence we have is a small clip like that, I'm gonna guess there was a reason it was prompted.
I will also say that in the past, a lot of people looking to kick up **** in the places I worked (especially in late 2020 and most of 2021) were wearing the same hats. Sure, Knoxville dealt with two large instances of BLM 'protestors' damaging store fronts, but if you were kicking out someone for coming in, going full Karen over masks/seating/whatever itched their asshoIe that particular morning, it was a person over 40 wearing a MAGA hat.
Not saying this was the case everywhere, but it certainly was in recent Knoxville history. The MAGA hat is now in the same league with a person carrying a "service" chihuahua in their purse, a person still wearing a mask, a person with a fistful of promotional coupons, a person claiming to be a restaurant reviewer, a person reeking of Aqua Velva, someone (who 9/10 times isn't celiac) waiting until sitting down asking for gluten free options in your Italian concept... if you see any of these people enter your restaurant, there is a collective eye roll followed by a groan in anticipation of some manner of bullsh*t you are all going to have to deal with.
Anyone wearing politically activated attire is already looking to be obnoxious. I don't care if you agree with said attire or not. It screams "I am going to push my nonsense on you and you have little to no say in the matter."
