Earlier, I got into a lift from the basement parking. It went up a floor then opened and a lady got it. But the doors wouldn’t close. We decided it’s out of order so we got out. But as soon as we got off, the doors started closing. Figuring it’s not broken after all, I extended my trusty Starbucks bottle between the closing doors to reopen them. They didn’t stop and caught my poor bottle in a tight grip! I twisted and turned for what seemed like an eternity until I was finally able to pull it out. The door then closed and the evil elevator went up on its merry way.
UPDATE: I figured, it’s the reflective finish of the bottle that confused the sensors of the elevator doors.
