"I leaned in to take a sip, and I noticed something hit me in the forehead, and I looked at my husband like, 'What was that?' " Andrews told 8 News. "When I turned around, I saw the snake in my margarita."
She also told the outlet that she saw the reptile move and wrap around her straw.
Workers attempted to remove the snake with a stick, but to no avail. Another restaurant goer eventually grabbed the animal and took it outside.
"I left shaking, I was traumatized," Andrews told 8 News of the incident, adding that the restaurant offered to move her to another seat, but she decided to leave instead.
The owner of Patron Mexican Restaurant and Cantina told 8 News that the snake likely entered through an air conditioning unit. He also reportedly told the outlet that no precautions were being taken to keep the incident from happening again.
