No, I'm describing a documented fact of why specifically McDonalds has different pricing in different locations. It has been that way since basically forever. They are individually owned by franchisees and within a certain range do set different pricing in different retail premises. I don't like McDonalds but it's also very ignorant that people are treating this like it's something new.

Next I'm sure some people will discover and be shocked by the fact that the non-corporate-run starbucks kiosks in some major international airports (run by an airport catering/specialist service company) have different prices than their corporate-run local starbucks.

Now if the topic is, as someone else has described in other linked threads on the same topic that different people using the app are getting different pricing for the same store, that's new to me and certainly something to be concerned about. It sounds like what airline ticket booking/purchase sites are known to do depending on your cookies, IP, useragent, browser fingerprint, etc. Very slimy.
