McDonald’s managers were forced to turn away customers who walked to the fast-food restaurant today.

One even drove over the orange cones used to block entrance to the parking lot.

The problem was power – or the lack thereof – which shut down the restaurant and FastLane.

About 8 a.m. Thursday morning, a construction work inadvertently cut the power line to the transformer. The incident also wrecked the transformer, requiring new equipment.

The incident shut down the McDonald’s – “we can’t even brew the tea, said a manager – as well as the gas pumps and coolers at the Warrenton Oil FastLane.

The new transformer was in place and power was restored about 2:15 on Thursday afternoon.

McDonald’s officials praised the Ameren workers and electrical crews working on the job and said their customers have been understanding of the power outage.

“It was just a very unfortunate incident and we are very sorry for the inconvenience to our customers,” said one McDonald’s official.

The construction project will open a new, stand-alone McDonald’s facility about mid-summer.
