Thanking a Helpful Stranger

Someone helped you find your way or carried your bag, and you want to express genuine gratitude.

You
Disculpe, muchas gracias por su ayuda.
dees-KOOL-peh, MOO-chahs GRAH-syahs por soo ah-YOO-dah.
Excuse me, thank you so much for your help.
"Disculpe" is the formal "excuse me" and a polite way to get someone's attention or preface a thank-you.
Stranger
No hay de qué. Con mucho gusto.
noh ay deh keh. kohn MOO-choh GOOS-toh.
Don't mention it. With pleasure.
"Con mucho gusto" is widely used in Latin America, especially in Costa Rica and Colombia, to say "you're welcome" or "my pleasure."
You
De verdad se lo agradezco mucho. Es usted muy amable.
deh ver-DAHD seh loh ah-grah-DEHS-koh MOO-choh. ehs oos-TEHD mooy ah-MAH-bleh.
I truly appreciate it very much. You are very kind.
"Se lo agradezco" is a more heartfelt way to say thank you than just "gracias." Use it when someone has gone out of their way.
Stranger
Para eso estamos. ¡Que le vaya bien!
PAH-rah EH-soh ehs-TAH-mohs. keh leh VAH-yah byehn!
That's what we're here for. May it go well for you!
"Para eso estamos" is a generous expression meaning "that's what we're here for." It reflects the communal spirit common in Latin America.
