Same here with Tuxedo Computers, I had already removed the drive because that's standard procedure. If a repair shop ever asks me my password I'm just going to another one because that is to me a clear sign they're incompetent.
(to be absolutely clear: I recommend Tuxedo computers. They suggested I remove the harddrive when sending me shipping instructions, something I had already done, but I found it very reassuring they said so and hence recommend them to tech-illiterate family and friends as well)
