It's been only a week since the World Cup started, but fans celebrating the tournament are drinking so much that Moscow is running low on beer.

Some bars and restaurants in the Russian capital said they are running dry, but the bigger problem seems to be the fact restaurants are having trouble getting the beer from their suppliers, according to Reuters.com.

Deliveries are taking nearly 24 hours, which is longer than usual, because the suppliers' stocks are also running low.

"We just didn't think they would only want beer," a waiter at an upscale joint in the city told Reuters. “There are really a lot of people in Moscow ... and they are all drinking."

Another issue could be that before the World Cup, beer sales dipped by nearly a third due to increased regulations on sales and advertising over the past 10 years in Russia. Reuters notes brewers did not expect such a reversal of the trend this year.

The only good news for Moscow is as teams are eliminated from the World Cup, fans will likely exit the country.
