Cash boxes are located all over (maybe no more than ATMs in America) and I used my missionary debit card to get some cash. It's so strange to live in a cash society. There are no checks and, although I'm told some business establishments will accept credit or debit cards, I haven't seen one used yet. You can choose which language in which you want to communicate, so that's very helpful.
I have been told that you never hand money to a clerk. There is a plate and that's what you put your money on, and that's what the clerk puts your change and receipt on. I didn't know that until after I had handed the clerk money yesterday. Then, the 2nd store we went to, I forgot and handed her money. They did accept it, but it is not the way things are done here.
