WTF, Dude

I don't think I have any particularly accented English or that my pronunciation of letters, numbers, and words is really that far off from the standard American. However, according to OH SO MANY of these stupid "speak your answer into the receiver" automated phone menus, I must somehow have acquired innate knowledge of Swahili because no matter how clearly I say things, they NEVER GET IT RIGHT. WTF!!!!! It's so frustrating! What makes me wonder, then, is how people who really do speak with an accent ever get through those menus? Could this just be a conspiracy by The Man to make customer service inaccessible to 99.99% of the population?
