The problem is that everyone know that other cards are accepted everywhere apart from the olympics, or at least Mastercard is.
This is more like BMW deciding to sponsor the construction of a road and only allowing their cars to pass.

Denmark had something similar with Visa as well. Apparently it works since I am now very likely to get a Visa-card next to my Mastercard for those just-in-case situations.
I'm sure your card failed to work but I doubt it had anything to do with a big Visa logo on the machine.
