@rob it is true, I also encountered those excuses. Which is fine, because during daily business they might have not the capacity.
On the other hand, I must say it was very positive paying with Bitcoin in El Salvador:
- San Salvador
- Ataco
- Juajuga
- Zonte
- Tunco
In most cases it was Strike or Blink. One time it was Chivo App. My experience with Chivo ATMs was supee bad though..
