World Cup tickets, flights and hotel rooms are expensive. Then there’s the price of beer. And what about $75 caviar-topped tater tots or $40 empanadas weighing 5 pounds? Prices aren’t all that different from what U.S. fans would experience on NFL Sundays or college football Saturdays. But some international fans aren’t used to such pricing and are calling foul, especially over beer prices that top $20 in some cases. Europeans are used to paying a third of those prices. Offerings also vary wildly from venue to venue and reflect local traditions.
