But Friday, she didn't wait long enough, and the mastiff got trapped between the doors. Other passengers swiped their Stockholm Public Transport, or SL, passcards in a vain attempt to get the doors to open again.
"Not even the guy at the ticket window could get them to open," said Dahlstedt.
In the end, it took three people to get the doors apart and free Beizel, who came out somewhat paralyzed but at least alive.
Dahlstedt is critical of the gates, which have been replacing the older turnstiles, and says they should be much more sensitive so that they can open if someone gets stuck.
