I lived in El Salvador for 9 months,
and the crazy thing is that you can't find a decent coffee for sale anywhere in the country except right at the airport in a fancy cloth bag costing a fortune.
All the other coffee was pretty gross.
It's like they send away all the good stuff and the local people get the worst.
Sometimes people mix coffee with other things (corn I think) and serve it so thick that it's terrible, and I was surprised that even the small children drink it for breakfast.
