Sounds like the one that happened to me a couple years ago, riding to work.
The left turn into the store parking lot is less than 80 yards from a stop-sign-controlled right turn at a T intersection; in preparation to make that left after leaving the stop sign behind, I took the the left of the lane (my mistake, too far left, but...), only to have the b**ch in the car behind me BUZZ ME ON THE RIGHT, cut off my turn, and hurry her fat ass in the store.
Fuming, I walked the bike in the front door, saw her, and gave her hell; her determined response was, "You're supposed to be all the way to the right!" Even after barking about my making a left turn, she still believed I was supposed to stay right, wait for traffic to clear, then make my turn.
She still recognizes me when she comes in the store; clams up and frowns real quick, and beats feet for the door.
You better believe I use the left tire track for left turns NOW.
