West Ham United fans were left disappointed after their side's opening Premier League game against Manchester City last weekend.
The Hammers were beaten 2-0 courtesy of an Erling Haaland brace.
Not only that, but many supporters were left angry at the rise in beer prices at the London Stadium.
The price of the cheapest pint of beer for the game was a whopping £7.30. That's a £1.45 increase from last campaign.
An image has emerged which shows the prices for food and drink during the match. A 500m Coca-Cola bottle would set you back £4.50, while a 600ml bottle of smart water cost £3.20.
While West Ham are not happy with the prices, they don't actually set the prices at the London Stadium.
And the club aren't happy with the prices, either.
According to the Daily Mail, they are willing to sue the London Stadium about the prices.
It is reported that they are prepared to go to court to force a price change, citing the Comparable Clubs clause in their catering agreement with the London Stadium.
The prices at the ground should be a mean of the prices at Arsenal, Tottenham and Chelsea. That puts the cheapest beer at around £5.75 per pint - £1.55 cheaper than it is currently.
The club have raised the issue with catering company, Delaware North, and expect the prices to be changed for the UEFA Conference League match against Viborg on August 18.

West Ham's cheapest beer is almost a £1 more expensive than Arsenal's in second. Fulham and Leicester share third, with a pint of beer setting fans back £5.80.
At the other end of the scale, you can buy a pint of beer at Man United's Old Trafford for just £3.
While a pint of beer will set you back £3.30 at Liverpool's Anfield. Those prices are bargains compared to how much you are forced to pay for a pint at the London Stadium.
If West Ham get their way, though, we could see the prices drop considerably in the next week.
