Around 10 years ago, dh and I were running for a train along with many others, when one of the platform staff hauled him off the train for keeping a place for me (I was slower). When we objected politely for this, along with others who were being allowed to board, he told us that if we didn't walk away immediately he would call the transport police who would lick us up for a few hours just because they could.
We had dc to get home to so left, but complained to management who shrugged their shoulders. I've avoided Bristol stations ever since.
While we were sitting waiting for the next train, we were asked to complete a customer satisfaction survey. That went well for them.🤣
Locking innocent people up for a few hours because they can, isn't anything new.
