Many years ago, the NY Daily News Sunday magazine had a weekly contributors' page and this very question was asked. This was my 3rd place winner(I got a tshirt):
I have the amazing ability to find any short line in any store or bank and, simply by standing in it, make it come to a complete halt. I do not have to actually be at the point of service;merely going into line will cause complete stoppage. This power has been known to last as long as 20 minutes.
