Piedmont Police and Oklahoma County sheriff's deputies said they were concerned when Ashley Warden posted a picture to her Facebook page of a group of deputies dining at the Oklahoma City restaurant, WFOR-TV, Oklahoma City, reported Thursday.
"Stupid cops better hope I'm not their server," a comment in Warden's name reads.
Authorities said they were concerned about the incident.
"It could mean bad service," Piedmont Police Chief Alex Oblein said. "It could mean tampering with food. You don't know what it means. It just makes you a little weary."
Oblein said Warden has had previous run-ins with the Piedmont police.
"Those are Oklahoma County Deputies, [they] had nothing to do with Piedmont, but I guess she got a bad taste in her mouth for law enforcement in general," Oblein said.
A Chili's representative sent an email to KFOR-TV saying Warden has been fired.
"With the changing world of digital and social media, Chili's has Social Media Guidelines in place, asking our team members to always be respectful of our guests and to use proper judgment when discussing actions in the work place. When we find that team members violate these policies, they are subject to termination. After looking into the matter, we have taken action to prevent this from happening again," the representative wrote.
