In the US every gas pump I've seen (I have not check the majority of states, but still a good sample) has a sticker on it stating inspections and who runs the state department that inspects them. Usually it is a yearly inspection (at least according to the sticker, maybe they do it more often I don't know)
replyNot just gas pumps, but any measuring device used to determine the price of a metered product. The scales at the register at supermarkets also have calibration stickers in my state.
replyNow that you mention it, I've seen them at some grocery stores - but generally not in a place I'd be looking unlike gas pumps where is is right next to the price and so you won't miss it.
replyI don't know if other companies do this anywhere but if you live in Ireland. Diageo have roles for people to travel around the country doing precisely this.
replyah yes, the guinness vans, I do often see them out and about
replyYou're in luck. Measurement Canada has the authority to inspect pints. Typically they only act on complaints, though.

I have a feeling that if the USA did random, surprise inspections on businesses to make sure what they were selling was actually as-advertised, the whole system would be exposed as fraud within a month.
replyI don't want my beer to taste like gasoline though.
