Finally I got myself a cash card at the bank called CSOB, which stands for "Ceskoslovenska obchodni banka." It is one of the largest banks in Czech Republic. What's great about this bank is that it has a very sophisticated online banking capabilities. For instance, unlike Wellsfargo with which we used to have our main bank accounts, you can transfer money to almost any foreign bank accounts directly using the web interface. You don't have to go to the bank and fill out a sheet of paper specifying all kinds of detailed information about the transaction every time you want to send money to the foreign account. This is very beneficial for us, as we need to trasfer money to our US bank accounts occasionally.
One interesting thing that I noticed about the bank employees in CSOB is that they wear VERY casual. One of the ladies who helped us wore a tight top that almost showed her belly, short jean skirt with black tights underneath, and a pair of cowboy-looking boots. And... she wasn't that young, either. She looked like she was about late 30's to early 40's. She also wore a very blue eyeshadow above and below her big eyes. I would say not a typical attire as a bank lady in the US.
