I was on a business trip, had an accommodation booked for the night and my suitcase. When a game popped into my head:
1. deposit the key to my suitcase at a rest stop
2. go back to the accommodation
3. lock ALL my clothes into the suitcase
4. now the only chance to get my clothes back is:
to get out of the accommodation (2nd floor), get back to the rest-stop ENTIRELY NAKED and retrieve the key
