@dgar Remembering once travelling, and at the airport of arrival taking a similar-looking but wrong suitcase, with a number lock. At the hotel, tried to open it with the code I had memorized - no luck. Then I saw it was someone else's, and contacted the airline to find its owner (surely in the same predicament with my suitcase). While waiting, on impulse tried code 0000, and it sprung open!
