Lime?

I work in a fertilizer plant. Potash, DAP, Lime. The three I deal with primarily. I made up a form that I sent to the various plant managers to request the products needed from me. The form lists all three products. Today I get a phone call:

Plant manager: Do I use these GPS call sheets if I want to request lime?
Me: Yes.
PM: How?
Me: Check the box that says "LIME"

They make HOW much more money than I do?
