Beyoncé’s “Renaissance” tour paid $100,000 to keep all 98 Metro stations in the Washington, DC, area open for an extra hour on Sunday,

This, after her show at the outdoor FedExField was delayed because of heavy rain and lightning.

A news release from the Washington Metropolitan Area Transit Authority said, “Due to inclement weather that may delay the start of tonight’s Renaissance World Tour at FedExField, Metro will extend the last train by an extra hour beyond the extended closing previously announced. The additional hour will be funded by the Tour to cover the $100,000 cost to run more trains, keep all 98 stations open for customers to exit, and other operational expenses.”

The stadium also issued a shelter-in-place notice citing lightning in the area, before giving fans the all clear and allowing the show to go on.

CNN says the shelter-in-place order was lifted after an almost two-hour wait during which time several people were treated for heat exhaustion and one person was hospitalized.
