I was still half awake when Al called. He told me that he was stuck in the lift and I went from half awake to wide awake. I went out of the house (same lift level) and tried pressing the lift button to see if the door will open from outside. Guess not. So I called the lift maintenance toll free number for help. Within 30 minutes, Al was out of the lift.
Thanks to Al, I had a good laugh :p
