BERLIN suddenly got popular. And the locals don't like it. Not one little bit.

In fact, some Berliners are so sick of tourists that they have begun to hang signs up in the street telling “hipsters” to go home.

Which is a bit silly since Berlin is actually home to the Hipster Olympics held in July.

Stickers plastered all around Kreuzberg read, “Berlin doesn’t love you.” While on Friedrichshain signs sticking out of windows read, “Noisy tourists go home!”

A gallery in a trendy neighbourhood displayed a sign in the window for months that read: "Sorry, no entry for hipsters from the US".

Hipsters from Australia? We’re not sure if you are allowed either.

"We've seen people insulted for looking like tourists or get disparaging looks," David Schuster, an activist for a local leftist group that has launched a tourist-friendly awareness drive told Reuters.

"There's some resentment that tourists party loudly or throw up on the streets," Mr Schuster said. "I think many Berliners do too, but they feel entitled to act that way."

So every nationality gets drunk and throws up on the street in Berlin, but it’s just German’s who are allowed to do it.

Tourism generated an estimated 10.3 billion Euros for the Berlin in 2011, which is about 10 per cent of the city’s budget.

Considering the woes of the Euro at the moment, that’s quite a few billion Germany can ill afford to lose.
