The giant reptile triggered panic after emerging from a nearby canal and rushed into the 7-Eleven store in Nakhon Pathom, Thailand on Wednesday.
Staff and customers hid behind the counter as the beast rampaged through the store and threw cartons of food and drink on the floor.
A salesman then alerted the police who arrived with tools capable of controlling the reptile, the Sun newspaper tells us.
In the clip, recorded on April 6, the lizard walks around in front of bewildered customers.
The lizard makes its way through the establishment, climbs the shelves. He then rushes over the shelves, throwing the products to the floor as they go, customers shouting in the background.
