I had to use my lockpicking skills when my grandma moved across country to live with my mom. She put her stuff in a "Portable On-Demand Storage" container and accidentally put the key to the lock with her stuff inside the container.

Luckily, she used the shitty round lock that a lot of storage companies recommend. I was able to pick it in just a couple minutes. Someone like LPL would have had it open in mere seconds.
