Last time I was in Puerto Plata, I went to the bank and asked the motoconcho to wait for me. I stood in line for about 20 minutes and when I got to the teller I gave her a note and asked for coins so that I could pay the motoconchos. With a confused look on her face she told me that the bank didn't carry coins. If you can't get coins from a bank where do you get them from?
