Paying with Cash and Getting Change

You pay with a large bill and need to make sure you get the right change back.

You
¿Cuánto es? Solo tengo un billete de quinientos. ¿Tiene cambio?
KWAHN-toh ehs? SOH-loh TEHN-goh oon bee-YEH-teh deh kee-NYEHN-tohs. TYEH-neh KAHM-byoh?
How much is it? I only have a five-hundred bill. Do you have change?
"¿Tiene cambio?" is essential when paying with large bills. Small vendors often struggle to break big bills, so carry small denominations.
Cashier
Son ciento ochenta pesos. Sí, aquí tiene su cambio: trescientos veinte.
sohn SYEHN-toh oh-CHEHN-tah PEH-sohs. see, ah-KEE TYEH-neh soo KAHM-byoh: trehs-SYEHN-tohs VEYN-teh.
It's one hundred eighty pesos. Yes, here's your change: three hundred twenty.
"Su cambio" and "el vuelto" both mean your change. "Cambio" is more common in Mexico, while "vuelto" is widely used in South America.
You
Déjeme contar... sí, trescientos veinte. Perfecto, muchas gracias.
DEH-heh-meh kohn-TAR... see, trehs-SYEHN-tohs VEYN-teh. pehr-FEHK-toh, MOO-chahs GRAH-syahs.
Let me count... yes, three hundred twenty. Perfect, thank you very much.
It's perfectly normal and expected to count your change in front of the cashier. No one will find it rude.
