If they ask why you want it tell them you have no fucking idea. You work for the purchasing department and you do not know the first fucking thing about all of the shit you order day in and day out. Tell them the requisition was signed off by the project manager, and the vice president of the department, as are all of the requisitions that you process, whether it be for a pallet of paper towels or six drums of iso-safrole. You do not have time to research what each of the hundreds of products you order on a daily basis is used for.
or at least in a perfect world,
I realize we all do not live in one,
