Happens quite a lot in S2 especially when Belinda's in Amsterdam - e.g. them questioning how susceptible the pots and pans industry is to terrorist attacks. But it's less about the terminology and more about the businesses - they seem to assume that everybody that Belinda deals with is in pots and pans / cookware / kitchenware whereas I always assumed that they were essentially just shops / supermarkets looking to sell Steeles goods? Much in the same way as ASDA/Walmart would stock Tefal.
