WATCH: You've been warned - Lion snaps at tourist with open window

If you encounter large predators while touring the Kruger National Park, you had better make sure your windows are closed - as this lion reminded a tourist.

Despite the male lion snapping at him, the tourist kept on filming, now through an only partially open window, until the lion walked off into the park.

"Even though I hadn't thought that I was disturbing him too much, it reminded me to always be respectful of an animal's personal space," the person taking the video told the Kruger National Park's YouTube channel.

This is not the first time lions have reminded humans that they generally don't like it when humans invade their space:
