Hi there. I noticed the suggestion to use the "shop=convenience" tag. But, the reason why I changed it to "shop=supermarket" is because, when I go to these places, I see they're big enough to be called supermarkets (in comparison with convenience stores, which are smaller) - and yes, there are trolleys available as well (of the smaller kind, at least). They're at the bottom of the list of what I would call a supermarket - but still, I think this term is more correct than a mere convenience store, because of the size of the places. Again, I say this because I regularly go to these two places (https://www.openstreetmap.org/node/3647434258 + https://www.openstreetmap.org/way/359658634). And, the reason why I didn't specify why I was changing the tags, is because I had the impression that no one was looking at these changes, in such a secondary city. But, I'll consider specifying the reasons for changes I make in the future, if I think they're important enough. This being said, there's another "My Auchan" in the city (https://www.openstreetmap.org/node/6430793477) which, by its size, does make me doubt the use of the tag "supermarket". And, I think that this is where the "problem" lies. Since, this last store is somewhere in the frontier between a supermarket and a convenience store. And, that's probably the reason why the wikis recommend the use of the tag "shop=convenience". I don't think I ever went to "My Auchan" stores in other cities, but I suspect that this particular chain is probably made of a bunch of stores that, by their size, vary between what can barely be called supermarkets and, in fact, convenience stores. So, this is a pretty "grey" area, I guess. If we're more demanding, in terms of the sizes of the stores and of the trolleys used in them, I suppose we can only call all these "convenience stores". But, as I said, when I go to the first two stores that I mentioned, at least, they're what I and everyone else in this city have always called "supermarkets". Maybe this a problem related to how small the economy in this city and my country is, and it all depends on what standards one is used to. But, again, the first two places at least, are what I'm used to hear being referred to, by other people, as "supermarkets". And, I suppose that, the best way to clear doubts, is by going to these places in question. I'll take better looks at them, the next time I go there, and I'll post here more information once I have it.
