In developing countries, individual ATMs may run out of currency, well before you hit the daily limit. To pay for language school in Ecuador I had to go to multiple ATMs and withdraw as much as they had in each one. Literally every pocket of mine was bulging with paper currency :/

I thought that Ecuador switched to use the US Dollar as their local currency in the year 2000. Was this before the year 2000? Or was your withdraw limit in USD tiny... or was your school bill huge (hardest scenario to believe!)?
