It isn’t easy work, being a full time professional spy photographer. Even though you work with your camera on public roads, sometimes you’ll have to endure abuse from the drivers of prototype vehicles. Skip to the 39 second mark of the video above to see a little spat between the driver of this next generation BMW 7-Series prototype and a spy photographer.

We asked a German-speaking friend what was going on between the test driver and the photographer.

Test driver: Put that camera away!
Photographer: I can take pictures. This is a public space.
Test driver: No, you can’t take pics of the cars without my permission.
Photographer: What’s your name?
Test driver: Go away!
Photographer: What’s the name of your boss? I’ve never experienced this.
