The one time I ever got upset at spanish speakers was the time in Waukegan I went into Dunkin Donuts and wanted to order something. I don't even remember what; it's about about 10 years. Neither the guy behind the counter nor his manager spoke English well enough to communicate. Pissed me off. At least, if you're going to be in a forward-facing customer-service position you should be fluent in the languages of your clientele.
No. We have no official language.
