You and me both, Roz: I have an unerring instinct for choosing the checkout line 30 seconds before the cashier has to switch with their replacement and balance out the cash register before going on break. But, yes, I will choose you or your equivalent if I have to cut through a line. Why? Because you are (a) a woman, (b) petite and unthreatening, and (c) you appear to be sane. I'll take my chances with you every time.
