Boys, please learn from my mistake. If you ever are in need of a sensitive or discreet transaction to go through without a hiccup (and let's face it, as degens, you have many), avoid Asian female tellers at all times! They have a need to be the office hero (be they at a bank, ** counter, or anywhere) and will try to apply strict scrutiny to your transaction. You need a friendly male white employee to assist you if you want competent service, without any questions. The black female teller at first glance seems like a safe choice as she will be too ignorant to know what you are really trying to do when you send money to Alvin Enrique Hernandez in Peru but unfortunately she WILL screw up some minor, but important, detail (like the spelling of a recipient's last name, contact info, etc).
Your safe bet is to seek the assistance of the white male teller.
