Well I have heard the "learn the language," argument my whole life. I usually hear this complaint from those who work in retail that have to deal with spanish speakers. Hey the customer is always right, if I was trying to sell a chinese guy something you better believe I would do my best to learn some chinese.

Then I hear whining from people who hear groups of hispanics speaking spanish in public. My answer is mind your own fucking business. If people feel more comfortable conversing in their native language that is their business. There are just some phrases in spanish that simply do not exist in english. Spanish is much more effective at conveying emotion, positive or negative.

Any other examples where people speaking other languages inconvenienced you.
