During Sunday’s season opener several restrooms at Chicago’s half-renovated Wrigley Field went out of service, causing long lines and forcing some fans to urinate in beer cups. Now the team has installed rows of porta-potties to serve as a back up.

Fans were furious on Sunday when several restrooms in the unfinished stadium went out of service early in the game. The final outcome only added to their woes as the Cubs lost to the Cardinals 3-0.

Full fans were forced to pee in beer cups and some even urinated in corners and on stadium walls.

Wrigley Field has been undergoing extensive renovations that didn’t get finished by opening day. The construction may last into June, officials say. The Cubs even announced that the last of the stadium’s new restrooms won’t be ready until then.

A second game with the Cards was scheduled for Tuesday but weather forced its cancellation. The Cubs bested the Cards 2-0 on Wednesday.

Using the time to good effect, the Cubs have now brought in porta-potties to serve fans since it will be many months before all the stadium’s restrooms are ready for use.

Chicago Tribune sports reporter Steve Rosenbloom criticized the team for its lack of planning.

“The Cubs knew they would lose stalls and troughs,” Rosenbloom wrote on Wednesday. “They knew it a month before the opener. They failed to plan for proper accommodations, so fans made urinals out of whatever was handy—empty beer cups, the ground, walls.”
