It's really fun to see the moment people realize things like this exist outside their bubble of knowledge.

I had some first and second-hand knowledge around pricing household appliances. There's a common assumption that "the manufacturer says 'charge X'", the retailer charges X+Y% and you all go home happy. And you could not be further from the truth if you tried: pricing is an insanely complicated process with negotiation from both sides and monitored by an army of secret shoppers to keep both sides honest.
