TIME:

On Wednesday, 18 workers were arrested for stealing the miniatures from LSG Sky Chefs, the company that provides food and beverages for American Airlines, CNN reports. The majority of those accused were LSG employees, but three were airport security guards. The arrests culminate a nine-month investigation known as “Operation Last Call” carried out by the Port Authority’s Office of Inspector General.Here’s how the whole scheme went down. At the end of every American Airlines flight, workers are supposed to return any unused bottles to a storage facility. Instead, workers began stashing the bottles to sell them to local liquor stores and bodegas.

I love those little tiny bottles of booze.
