Since many of us are not able to travel and are staying home, I thought it would be a good idea to start this thread. While traveling or in your hometown, people assumed you do not speak or understand their language and spoke between each other until you replied in their lingo. What kind of reactions did you get?

I'll start with a story of mine, I was in line for a ride at Universal Orlando and behind me was a Brazilian teenage tourist group. I am a fluent Spanish speaker, and can understand everything in Portuguese and speak decent enough.

One of the teens asks the other what time it is, to which the other replies "Não sei, pergunta o Albino gordo" (I don't know, ask the fat albino) and points to me. So the guy asks me the time and I tell it to them in English.

Line keeps moving and 10 minutes later the same guy asks me this question as a conversation starter,

"Do you speak Portuguese?"

So I naturally replied with

"Sim! Eu entendi tudo o que você diz!"
(Yes, I understood everything you said"

Suffice to say the whole group nearly soiled themselves when they realized their mistake
