Hey have you ever tried learning a second language? Its not that fucking easy.
I currently live and work in a spanish speaking county, although now I'm nearly fluent, i didn't speak a word of spanish when I got here. If it wasn't for the patience of everyone from bus drivers to MC Donald's workers to the police to my coworkers my time here would have been much more miserable.
I don't think in a year of being here has one single person gotten angry with me for speaking in broken spanish. For the most part they slow down their speech or toss out what ever english they know. They don't have too, they're just being nice; you should give it a try.
