After triggering the “emergency shutoff function” on the Tokyo Disney Sea roller coaster (what the attendant told us when I complained that my friend was claustrophobic and panicking, and that I was uncomfortable with the bars on my shoulders). He didn’t let us out for a while after that.
The ride shut off while our car was running, so we stopped where gravity left us (this photo). We were stuck and locked into our car for what felt like half an hour. No apology, just a ride ticket, this could have been handled much better than this.
