USPS drivers tossing piss filled gloves? Maybe.

The Consumerist received a disgusting tip + cameraphone goodness of a USPS driver having tossed a latex glove out the door filled with yellow liquid. The actual liquid could not be verified as actual urine, but it makes you think. When is there time to stop for a bathroom break when there are hundreds of letters to deliver by a specific time?
I’m nut sure if I saw this on a movie, or if I heard it from an actual person, but I’ve heard that some semi-truck drivers urinate into 1 gallon milk containers and throw them out the window on long hauls. Not sure how true piss jugs are on the freeway.
