It's not all rainbows and puppy dogs here in the UK either. I once got into a fairly heated argument with a 'Phones4U' employee when he tried to sell my housemate an HTC Wildfire. I'd told her specifically that the HTC Desire would be a good choice if she wasn't interested in an iPhone, and the salesman told her "the Wildfire was identical to the Desire".
When I pointed out that the Wildfire, whilst running the same OS, was a substantially worse piece of hardware which had been known to judder, crash and generally be a cheap entry point, not a quality phone, he called me an idiot and pulled out his own Wildfire to prove to me that it was 'identical'.
I pointed to the processor speed, RAM capacity and then when he still wouldn't have it used the screen size as proof. Eventually I just walked out after telling him to QUIT his day job
Edit: Meant to say, loving the premise of this thread, had about 3-4 great laughs at these stories, keep em coming
