People at work need to use the correct terminology for my department 😤

I run the mail room in procurement at my workplace. Obviously, my area handles the mail around here while shipping/receiving handles most of the packages. And every now and then, we'll get an email addressed to the whole department for something that needs to be "mailed out". Naturally, I assume that's my job, so when I show up at the department to pick up that item, they go and tell me they actually wanted it sent out UPS! Then they mean to say they want their thing "shipped out", not mailed out. Ask anyone who works in procurement, the two terms are not interchangeable! They are two totally different processes with two totally different carriers and two totally different areas of the department are responsible for them. It's so frickin' annoying! Sure, I could call them to be sure first, but when I get those emails while I'm out making rounds, I like to pick them up while I'm already out and about. Only to find that it's just a big waste of my time! 🤬
