Recently I was in a South American supermarket, a Bolivian supermarket in the city of Sucre to be more precise, waiting for my change. You’re probably thinking this seems normal enough and incredibly straight forward. You wait a millisecond for your change, the man/woman behind the till hands it over and BOOM you’re out the door with your shopping. Well, this is not the case in South America. As I was waiting patiently for my 3 Bolivianos change (that’s pretty much zero pence by the way) the man/woman behind the till started looking at me strangely and I thought uhoh here we go again.
