My iPhone was stolen by a random shady person who walked freely into the studio at night and easily came into the changing room without anyone stopping him. I had just finished a yoga class and i was changing my clothes. He grabbed my phone that was sitting right next to me and ran out. I was almost naked and couldn't run after him. the people at the reception didn't even notice this whole thing.
The studio never took any responsibility for it and when i asked them to check the security cameras they said it'll cost them a lot of money. the phone cost me 800$ by the way. I asked them to maybe do a better job at vetting people who walk in to avoid stuff like this from happening, they were surprised at my suggestion and said they can't do anything about it. One of these days, some mentally disturbed person will walk into the girls changing room and commits something far worse than stealing a phone. It's a disaster waiting to happen. Avoid at all cost.
