BOULDER, Colo. — Home Depot was sued by a shopper who claims he got stuck to a restroom toilet seat because a prankster had smeared it with glue.

Bob Dougherty, 57, accused employees of ignoring his cries for help for about 15 minutes because they thought he was kidding.

“They left me there, going through all that stress,” Dougherty told The (Boulder) Daily Camera. “They just let me rot.”

The lawsuit, filed Friday, said Dougherty was recovering from heart bypass surgery and thought he was having a heart attack when he got stuck at the Louisville store on the day before Halloween 2003. A store employee who heard him calling for help informed the head clerk by radio, but the head clerk “believed it to be a hoax,” the lawsuit said.

Home Depot spokeswoman Kathryn Gallagher said she could not comment on pending litigation.

The lawsuit said store officials called for an ambulance after about 15 minutes. Paramedics unbolted the toilet seat, and as they wheeled the “frightened and humiliated” Dougherty out of the store, he passed out.

The lawsuit said the toilet seat separated from his skin, leaving abrasions.

“This is not Home Depot’s fault,” he said. “But I am blaming them for letting me hang in there and just ignoring me.”
