Brett , as you found out a lot of banks would never have see a sterling note , outside of the larger cities and branches , probably thought it was play money , ha ha , they prefer us$ then they can loan it back to the U.S.A. with good interest .
I have a separate linked Aussie cheque and debit card account which my boss { Ying} can access via a permanent arrangement with a plastic card , via the atm at her local bank as I am only transferring money online between accounts she could make a withdrawal within minutes if it was required , when I go to China apart from a few hundred RMB , I always withdraw with my cards from atm,s enough for 48 hours , that way I have never had a problem and even for business do not need to open a local account , regards Ying and Robert .
