Recently buying computing hardware I selected an American provider for my eu based lab. After paying the invoices the bean counters then asked if I could get the money back because they didn't want to pay VAT. I said feel free to ask for the money back yourself I'm happy with the purchase that you already approved. They refused and kept going up the chain until the director said just pay the VAT. after countless emails, meetings, and other time wasting activities, VAT ended up being 8 euros. Bean counters create drama to justify their bean counting.

I'm sure there are good reasons for them. But they are often simply in the way.
