After a dispute over diced onions on a breakfast sandwich, two men threw a snake over a counter towards an employee of a Saskatoon Tim Hortons.

According to Saskatoon police, staff members “fled the store in fear” after the incident, which took place Monday around 7:30 a.m. at the Tim Hortons in the 600 block of 22nd Street West.

“I’ve never heard of a snake being thrown at an employee by a customer … It was definitely a little chaotic,” said Saskatoon police spokeswoman Alyson Edwards.

“The staff was shocked and afraid and fled the store.”

Staff told police that two male customers were arguing with an employee about their breakfast order – specifically that they wanted their onions diced. When the argument escalated, one of the men reached into the pocket of the other man, pulled out a garter snake and threw it behind the counter.

No one was injured, said police.

Officers quickly found the snake and determined it was not venomous, said Edwards.

The two men, both 20, are facing charges of mischief and causing a disturbance.
