The biggest problem will be the quality of supplies, as sanctions will damage the supply chain.
What quality? Even in Austria, at some really busy McD's I've been to like the train station or airport, their finished burgers looked nothing like the ones in the menu.
Often they had components like the cheese, lettuce and sauces missing and I got just a dry paddy between two barren pieces of bread as a burger lol. It was uneatable so I had to throw it away and buy a sandwich from the SPAR next door which has much better quality.
The McD's I've had in NY weren't much better either.
OTOH, McCafe's in Europe (the separate establishment, not to be confused with the coffee you can get from McD's) are amazing, coffee is always great, on par with even fancy hipster cafes and their pastry and cakes aren't bad either.
This is surely too high a standard!
Did Coke ever give you the satisfaction of the people in the Christmas adverts?
Did you get girls after you bought Lynx?
Did you score more goals with those Predators?
Sure, I get it, having underpaid and overworked people making your food is not a recipe for a great experience, but ultimately I paid in full, the company got their money and I didn't get the product I ordered, which is why I jusy stopped eating there, since I don't like being "THAT GUY" who ask for "the manager" in order to complain about overworked people on minimum wage that they got his order wrong and they need to redo the order while 10 more customers are waiting in line.
Like buns and meat and so could be sourced locally. But spice (mixtures) may have been imported and the mixture recipe is locally unknown.
However that could creates some creativity in place and create similar, but different (better? Worse? Who knows) products.
Compare this to Coca Cola in Germany during WW2. Due to the embargos they couldn't deliver the "secret syrup" so Coca Cola Germany used some "fantasy" and created (the predecessor of) Fanta, which nowadays is a brand of Coca Cola served in multiple countries (with differeing recipes)
Fanta is now nothing special either, just a sugary fizzy drink with orange flavoring that can be done better by other local companies.
Coca Cola is just a branding and marketing juggernaut at this point, but their drinks themselves are easily replaceable by better local alternatives at any time.
Come to think of it, banning Coca-Cola could actually be a health benefit for the population lol.
I remember that in Mexico there are poor villages addicted to Coca-Cola where the company uses local water to make the drinks and the villagers have no access to clean tap water and have obesity and diabetes from all the coke they drink, and all is sponsored buy the Coca-Cola and their lobbying. Absolutely disgusting.
I myself spend some time in bread and a part of the taste of bread comes from my bacteria/yeast culture growing here at my place, feeding of stuff which is in the air at my place. If i go elsewhere that already changes to a small degree. If I vary temperature, humidity of air ... this has impact. On industrial scale the impacts are way more as they use processes to ensure the end product stays as much the same as possible independently from changes to ingredients (natural products change with each harvest ...) and where it is processed further (a Big Mac is, by McD, supposed to be as equal lgibally as possible) this is done by having Enzyms, chemicals and other comments doing their work.
Deglobalization means you can't travel to Russia ;)
(Not sure if Americans can visit the place. There are downsides to deglobalization too...)
In case it refers to McDonald's: They already did. https://www.mashed.com/202684/the-real-reason-mcdonalds-got-...
