A San Antonio, Tex. man had quite a creepy encounter inside the men's room of a local Starbucks when he encountered a rat snake wrapped around a toilet, San Antonio station KSAT 12 News reports.

Bruce Ahlswede had just finished a business presentation when he entered the bathroom to find what initially thought was the work of a prankster, but when it moved, he knew then that it was the real deal and immediately notified employees.

"I said hey, you know you've got a snake in your bathroom and she's kind of freaking out," Ahlswede said to KSAT 12 News. "So we went back in and watched it as it slithered back and around and down underneath the rim of the bowl and right inside."

His wife, Michelle, snapped a photo of the reptile before it slithered back down the toilet, which she then of course posted to Facebook. "Bruce went to the little boys room and got a big surprise," she wrote of her husband's creepy encounter.

"I don't think I will ever get up in the middle of the night again to pee," one person commented, while others expressed that toilet snakes were a huge fear of theirs.

"A lot of people were really freaked out and some said thanks a lot, they were over their phobia of this ever happening," Michelle Ahlswede told KSAT 12 News of the incident.

Based on the photo that Michelle Ahlswede managed to take, experts tell the local station that the reptile was most likely a harmless rat snake, the most common non-venemous snake encountered in North Texas, according to the University of Texas at Arlington's Amphibian and Reptile Diversity Research Center.

Last week, the Huffington Post reports, another man found a dead rat snake wrapped around his bottle of Bud Light that he'd just opened from an 18-pack.

"There's no way I was going to drink the beer," he told ABC Local. "It stunk bad. The snake was dead. The snake was ice cold. It's kind of shrunk up and the eyes are missing out of it."
