No, actually I am not kidding. I haven{t been here long enough to get an actual on ground feel for it but I can say that I am paying ín pesos about the same for a cup of coffee that I did six months ago. I know for sure on the ground in Europe before I left the cost (in local currency) for food had gone up in the same time frame.
All the money printing going on (us and europe at least) is having an effect, how far and deep that ripples out ...
You must frequent a pretty desperate coffee shop. Or one with such massive margins that they're willing to absorb the losses from inflation & devaluation just to keep customers happy.
In most places that is not the case. 6 months ago I was paying 22 pesos (and 12 months ago 18) for a 20oz drip coffee at Starbucks; currently its 28 pesos.
On the other hand, a 20oz (600ml) drip coffee at starbucks in the US costs the same as it did 6 months ago and the same as it did 12 months ago and the same as it did 24 months ago.
