When I was living in Argentina... I would withdraw the money from inside a local mall...keeping an eye out for who might be watching. Like many things in Argentina... the policy actually goes against what makes sense in practice. The excuse the banks/government give for 300pesos per atm withdrawal "is for your protection". The reality is for them to ream you for the charges. To stand at an ATM for 5 minutes...making withdrawal after withdrawal to get your 3000pesos rent money... attracts attention from thieves... but as long as they get their 5U$S for every 300pesos (50U$S in charges in 5 minutes)...this will not change
