Pulling up to runway at an uncontrolled airport a few weeks ago a guy makes a call "7 miles out, on right base for 05". There was another person in the proper pattern on a left base, so we held short and waiting for that guy to land. As he crossed the threshold we see the plane coming in like a bat out of hell on the right base, and then we hear a call, "left base for 05". I asked " do you mean right base?", and got a "No, I'm on left base" back. So I continued to hold short and informed him of the traffic on a right base nearing the turn to final. Crickets from the radio..... He comes blasting in and slams on the brakes and gets off on the first turnoff. There is no other plane in the pattern.
I wanted to ***** him out something fierce, but I only said "this field is left traffic for 05 due to skydiving operations south of the field" and left it at that. The jerk just did it to land in front of me getting out..... But I held my tongue.
