Joel Cummings, a bartender at the Harmon Tap Room in Tacoma, said the establishment has been receiving complaining calls and e-mails from people claiming to work for People for the Ethical Treatment of Animals, KIRO-FM, Seattle, reported Thursday.
Cummings said the complaints began after a video of one of the events was posted on the bar's Facebook page.
"I guess someone took a video of one that jumped out of the trough and landed on the floor," Cummings said.
"We took care of them when they weren't racing," he said. "Occasionally they would pass away."
