Crossing the border with salvia

One thing Americans don't suffer and I don't think they even have idea about is the Border Patrol's behavior when dealing with immigrants, legal and illegal ones.

I won't talk in general, but what happened to my person.

Last occasion, when crossing the border as part of my job with salvia extracts, I had to go to the border office for a I-94 permit, a person that looked Asian interviewed me, and I think he didn't know enough Spanish. He asked for a proof of address, but I didn't understand him, until finally, I got it, and I gave it to him, but the problem was that every time he asked for the same thing, he was louder and meaner, after I gave him the proof of address, he was asking for my destination, same thing than before, I didn't understand at first, and he got angrier, and on and on, he almost didn't give me my permission because no good reason, I just couldn't understand his bad Spanish.

Later the same day, we were traveling to LA, we were stopped for a Border Patrol's revision right after San Diego, and the officer, with a despotic behavior, he asked for our ID's. One of the passengers showed him his ID proving the he was born in the US, but the officer was wondering why he couldn't speak English (of course in English), 2 or 3 times with a loud voice, after a long discussion he finally let him continue the trip with us. In the end the agent hit the Van's side as showing his anger because he didn't catch or scared anyone.

I'd like to know your opinion about this, and my opinion is that this is not a good way of treating tourists, specifically the ones who care about laws in America and obey them by getting our Visa and necessary permits to enjoy this great country. Because of this, I don't want to think how illegal aliens are treated, but I'll talk about that later.

Wish you great life.
