And I just had two withdrawals at Citibank ATMs in Buenos Aires both of which show as "NON-CITIBANK":

*NON CITI ATM CASH WITHDRAWAL
AT CITIBANK ARGENTINA Av. Santa Fe 3168

CASH WITHDRAWAL AT NON-CITIBANK ATM
Florida 746 Capita

First one already got charged the 1% fee, the second one was only yesterday so I am sure the fee will post in the next few days.
