I had issues at Luton a few years ago. It all boiled down essentially to the bloke wanting to feel important and saying all photography was banned unless he allowed you to. Thankfully I was only passing through.
Liverpool Central I also had a weird incident around 2016 where, having gone down to the platforms, took a photo of my train then boarded, a staff member chased me onto it and told me that was banned because I might be a terrorist (!)
I remember back in 2017 when I was on the Madrid Cercanias network, I sauntered to the back end of the train I'd just left, only to be chased by two security guards, followed by a collective "ohhhh" as I spun around and took a photo of the train. Photography, surprisingly, was perfectly fine by them, they just thought I was off for a wander down the tracks!
