We have a guy at work who drives a full size pickup. Quite a few people here do, actually, including myself. Everybody, except this one guy, knows how to park it within the confines of a single parking spot. I have never seen this guy take up less than 2. This is not an exaggeration. Every time. Today he parked directly in the middle of 2, with the back end hanging 1/4 into 2 other spots. What's the tactful way to say, "Dude, you park like an *******?"
Edit : He's also the type who has no need for a full size pickup. Myself, I do a lot of woodworking and routinely haul 12+ ft boards of hardwood, or multiple sheets of plywood. Other people here hunt, farm, etc. This guy is a 60 year old loafer.
