What are you supposed to do if the fare gate is not working?
On my last trip we encountered a fare gate that was out of service. The exit doors were propped open and everyone was using it to enter. At the time we didn't think anything about it and just continued with our trip. On a different metro ride we did encounter a ticket check while changing metro lines. This was the first time I had ever seen them. We showed our validated tickets and went on our way.
So what should you do if the gate doesn't work? I don't recall if there was another entrance to use. The ticket booth was not staffed.
TIA
