Ha!
I work at a chemistry (nanotechnology) company and manage the Characterization Service department and interface directly with customers who want their samples analyzed by Electron Microscopy (TEM). Mass Spec. (ICP-MS) and other techniques. Fortunately my customers typically already know what they're dealing with and what they need. Leads to some interesting studies and solid relationships across varied industries.
Our Sales Team supporting our product sales (much higher revenue) - now that's a different story. Some of their customer inquiries range from ignorant/stupid to just plain bizarre... I'm definitely happy I don't have that job haha - sticking to Analytical Chemistry. Takes some patience!
