Miami vacation/English vs Spanish

I have now been to Miami 3 times for vacation coming from the Rocky Mountain West. One thing I’ve noticed is that a large majority of the Latin people are very rude when they automatically start speaking to you in Spanish and they then realize you don’t speak Spanish. They act like you’re out of line or something for not knowing Spanish. I went to a fast food place and the gal didn’t know English I asked her if anyone in there knew English so I can explain my order better and she looked at me crazy and said “No”. Same thing happened to me at the gym. I realize English is a second language there but it just baffles me that people aren’t more polite. And why is everyone so rude on the streets when you are walking nobody says excuse me and nobody will move out of the way of your path of travel.
