I asked a few of the people who spoke English about the effect of the US sanctions on Russia, they didn’t even know about them.
The shelves are full, the stores are all open. There is no “run” on products.
I still see a extraordinary number of American brands here. Coke, Fanta, KFC, Burger King, Fridays (without TGI), CitiBank, etc. Some have just changed their name, Starbucks is now Star Coffee, same logo.
The name change is “virtue signaling,” saying something publicly, that seems to be a positive but really has no meaning. Like changing you Twitter icon to a particular color or wearing a pink ribbon for “awareness.” (Who isn’t aware of cancer?) These companies are using the media and the media’s hype to make the consumers think they are socially responsible than their competitors. Really, they just want to appear to care.
If they can sell you an extra can of soda or get you to super-size, because they’re the company that matters, then they’ve done their job of scamming you out of your money.
My understanding is that no American credit or bank card will work in Russia, I haven’t tried, so can’t confirm.
Much like the Cuban embargo, it is only the US participating, so little effect worldwide.
