Can you break a fifty?

Hey everyone, sometimes when you're in North America, you have a big bill like a 50$ or a 100$bill and if you go to a small shop or convenience store you might want to ask them:

Can you break a fifty?

meaning

Do you have change for a 50$ bill?

Many small shops often have limited change so you will see a sign on the cash register that says they don't accept 100$ bills. Shopkeepers will get angry when you want to break a large bill and you buy a 1$ pack of gum. They might even refuse your purchase! So it is a good idea to politely ask them first:

Can you break a hundred?

Have a great weekend,
