Trying to buy a laptop from Tiny Computers in England
When I moved to England, I tried to buy a laptop from a company called Tiny Computers (now defunct) and the PFY who was dealing with me refused to move on from the "No" answer when asked if I wanted the extended warranty (which he must have gained commission from). Eventually I said "if you do not move on from the question of the warranty, I will walk out right now". He moved on but tried to come back to the question later, so I walked out of the sales office, and ordered the laptop from their website on my credit card.
