Industrial waste Puns

Alright so quick synopsis of what I do for a living is treating industrial waste water for oil fields. Part of our process is removing solids from the water and using a hydraulic press to squeeze the water out of it and dispose of the dry cakes. Once a day, a waste company rolls in large trucks to remove the big bins where we store the cakes, and put in fresh ones.

Today I was talking with the driver of the truck as he replaced my last bin. I wished him well on the road since we live in California and lordy knows nobody understands how to drive in the rain. As I was turning away from him I said

"If you'll excuse me, I have more pressing matters to attend to."

And immediately started up the steps to our press building, laughing the entire time.
