DIN stands for Deutsche Industrie Normen, German Industrial Norms, but
is today a universal standard and "DIN" is a universal description.

Any, ANY, DIN fitting/requirement/engineered thingy has to be
according to the standard and the standard allows no deviation. That's
why it's a standard.

You're right, the people in the shop are dead set wrong. Their BS is
positively dangerous.
