This guy gets his arm unexpectedly covered in deer snot.
Wildlife can be unpredictable at times, and unfortunately for this guy, he finds out this out hard way when a buck sneezes on him.
It could have been worse, obviously. He could have been bitten, or the buck could have decided to put some holes or racing stripes in the door with his antlers.
I don’t know for sure, but this looks like one of those drive-through zoos to me. There’s a reason they tell you to keep the windows rolled up I guess! The least he could have done was hand the buck a tissue.
