Blah - thanks, I've been living here for 2+ years so I'm pretty aware of the precautions. I do it, I just don't like to. But I wanted to give people a heads-up that if they have a Citi or HSBC account, they can take out more than 300 pesos per day.
Edited to say - you do need to be careful though. I just took out 3,000 pesos at a Citi yesterday. The ATM only gave me 500 pesos but charged my account for 3,000. The bank manager was actually very helpful and did all the paperwork and got me the remainder of my cash but you don't have a guarantee that the transaction will be easy. Obviously if you're going to do a large withdrawal, do it in a branch DURING biz hours in case there are any problems.
