Transacting financial business is quite different here.

When you enter a bank, there is a security guard who opens the door for you. You then walk to a machine that asks you what type of transaction you would like to do, like make a deposit, withdraw cash, open an account, etc. You indicate your choice and a ticket comes out with your number on it.
You then sit and wait for your number to be called, telling you which station to go to. When your number is called, you go to the proper station and the transaction proceeds.
Sometimes you don’t have to wait a long time, particularly if your transaction is an easy one, like making a deposit or withdrawing money. Sometimes you have to wait a long time, such as if you’re opening an account or something else that will take some time.
Whatever transaction you are doing, be sure to have your passport! When you finish, you bow, hands together, in thank you. Same to the security guard at the door.
Most of the time you don’t need to visit the actual bank. There is an ATM machine in the lobby of our condo building, for example, where I can now use my bank debit card to get cash. There is also a phone app for each bank where you can do a lot right on your phone. 🙂
