The video, posted to YouTube by Sary’s Siem Reap Tours, shows the tour guide pull his vehicle over so his passengers can get a closer look at a monkey “hitchhiker” at the side of the road.

The monkey confidently approaches the vehicle and climbs on the front, grabbing a pair of water bottles from the driver’s basket.

“Just one!” the driver says, but the monkey doesn’t seem to care. The thirsty simian grabs both the bottles and takes a sip.

“My customers wanted to meet some of the famous monkeys of Siem Reap. We met up with a thirsty friend,” the tour guide wrote.
