We'd been instructed to get our VAT refund at our last stop in the EU, which is the Netherlands. We knew that we had to have our official tax forms with receipts attached, passport, boarding pass, and merchandise for inspection. We spent 10 minutes walking to the customs station which was CLOSED, with a sign redirecting us to lounge 3, another 15 minute walk. At lounge 3 we had our forms stamped by customs. No problem. We proceded to the Global Blue counter where we received a refund of 13 euros. The balance of our refunds, about 40 euros, had to be made at a different counter, ANB-ANRO. There was one clerk on duty for the entire line. In the middle of his transaction with the person ahead of us, he decided to take a tea break! We could clearly see five other employees, all taking a tea break at the same time, no one helping the customers who had planes to catch. He finally returned to his station, dunking the tea bag, taking sips of tea. He call us, inspected our papers, and then asked for "the second copy" of the VAT forms from Germany. We told him that they only issue one form. We purchased many things in Germany and in every instance only one form was issued. There was nothing on the form saying that two were required. Mr. Tea Drinker said it was ABN-ANRO's "policy" to require two copies of the form, pushed our papers back at us and said he couldn't help us.
In an airport with millions of signs and diagrams, the VAT refund information was nowhere to be found. The information desks gave out the wrong information. The entire concept of having tourists run from one lounge with closed windows to another with customs to a third with bank tellers is telling me that this is not designed to refund your VAT - this is designed to NOT refund your VAT.
Based on my experience I advise that you either avoid making purchase decisions based on promised VAT refunds which do not materialize because some bureaucrat is missing a signature, a copy or a stamp - or to avoid trying to claim these refunds in the Netherlands.
