Or like that one time where I put my shampoo and conditioner in baggies so they wouldn't spill over my luggage, and TSA took them out to test the liquid, THEN PUT THE DE-LIDDED CONTAINERS BACK IN THE SUITCASE WITHOUT THE BAG.
Wasted all my shampoo and conditioner, and I had to do laundry in the shower on vacation because there wasn't a washer available.
