This is the shocking moment a snake slithered under a woman's chair as she sat outside a shop.

The 5ft rat snake emerged from a closed storage room in Nakhon Ratchasima, Thailand, on October 28.

Footage shows the reptile gliding towards the woman. A man noticed it near her feet and alerted the group, prompting her to immediately lift her legs and place them on the bench.

The snake then flinched, causing it to dash back into the storage area. A bystander attempted to poke it with a stick, but it was too late, as it had already retreated.

The Thai Rat Snake is a non-venomous species that poses no threat to humans. Fortunately, the woman did not sustain any injuries or bites from the encounter.
