@saintajax33 I believe those are specifically for tourists in places like Cuzco who are unused to the altitude. But certainly they'd sell us the air we breath if they thought they could get away with it.
@RabbaRab @avon_deer the altitude thing makes sense, but I nowhere that high up.
@saintajax33 @RabbaRab i have never been to Bolivia or Peru but I suspect if I did I'd prefer the local remedy for altitude sickness; cocaine tea.
@saintajax33 @RabbaRab Yes..at lower altitude cities it IS basically just a gimmick.
