This reminds me of the day a Chick-Fil-Et opened in a town near me. Same day: White Supremacist protest comprised mostly of beta-men, morbidly obese fat women with colored hair, and some very old dudes. They were recording everyone who interacted with them.

They weren't FBI agents, but I'm fucking sure they were Leftists trying to smear the restaurant, and to visually identify anyone who agreed with them later as a target to attack.

Same thing is probably happening here.
