Imagine you doing that to somebody who only speaks spanish. You want to say excuse me but they had no clue about what your saying.
Here are some ways to say Thank you, excuse me and please.
Thanks a lot
Thank a million
No hay de qué
When you want to say please. You simply just say Por favor . How easy is that?
Con permiso. (Someone’s in your way)
Disculpe. (Get attention)
Perdón. (When you bump into somebody accidentally)
All of these are good ways to some thing if you want to reply nicely to someone who speaks spanish.
You're walking down the hallway and someone knocks your book out of your hand. You ask someone else to pick it up and then you thank them.
