This reminds me of when I bought my Technikardan which was from a shop in Germany. I made a list of everything I thought I needed and ordered it all from the shop. I asked the guy, who spoke basic english, if there was anything else I would need. He said I would need some clothes which I thought I was a very odd thing to suggest and I declined. After I left the shop I realised what he meant which was a dark cloth. I got a call a couple of weeks later to say everything was ready and went to collect the camera.
The assistant had obviously realised I didn't understand what he meant and had looked up an alternative word. When I got to the shop he asked me if wanted a rug to put on my head. I just burst into laughter. I don't think he understood why. In the UK a rug for your head is slang for a toupee (hairpiece).
