Bungle, just because we have a custom in this country doesn't mean it will be the same worldwide, so why the WTF?
Again Bungle, the whole world doesn't operate the way it does here. Sure, most countries use non-geographical numbers for mobile/cellphones so you always need the area code but a few countries (the USA being one) use the same area codes for landlines and mobile/cellphones. http://www.howtocallabroad.com/qa/cell.html
