Take 20 dollars plus coins with you.
We live in a world where online payment is available everywhere, even in small amounts. Paper money, however, you can always use even if there is a malfunction at an ATM. Make sure you always have 20 dollars and some coins in your wallet in case you can’t pay with your debit card. Also discipline yourself not to spend it when it suits you. Really save it for when you can’t pay any other way.
