I worked at Argos on weekends when I was a student. They provide absolutely no training on the contents of their catalogue, so whenever anyone had a question about a particular product, we'd go and fetch whoever it was in the stockroom who was into the product in question. Me - hifi, computers, musical instruments. A bloke who was doing a plumbing course was an expert on washing machines and dishwashers. Baby stuff? Better send them over to the jewellery counter to talk to the new mums.
