In 1901 a Swedish immigrant to America called Johan Nordstrom founded the Nordstrom department store. In 1975, by now a national chain, a Nordstrom customer walked into one of their stores to return a set of tyres he’d bought. The salesperson gladly took back the set of car tyres and gave the customer a refund. Nothing weird about that, right? Except Nordstrom has never sold tyres.
