The fact that AAA uses your area code to determine where you are and sends you to that regional office. This may have worked back when everyone was using a landline and so, the area code really was where you were. Nowadays, of course, the area code on a cell phone likely has NOTHING WHATEVER to do with where you are.
I managed to lock myself out of my car for the first time in about 10 years the other weekend. I'm in Virginia, my cell phone still has my number from Los Angeles. I called AAA to come let me into my car. Got put on hold for 20 minutes. A nice woman comes on the line, gets my member #, car info, etc. etc. and finally asks what city I'm in. I tell her. She gets all confused and we go back and forth in a completely non-productive conversation for about another 5 minutes, before I finally say that I'm in My City VIRGINIA. Oh! she says, this is the Southern California office, you want Mid-Atlantic. I'll transfer you.
So I spend another 20 minutes on hold before getting the nice person in the Mid-Atlantic office and they managed to send out a locksmith for me, who then made a number of fairly offensive sexist/racist comments to me while opening my car.
Fortunately, there was a restaurant next-door, so I was able to have lunch while waiting around. The whole incident took about an hour and a half from the time I realized I'd locked myself out.
