I never cease to get a kick out of patients who try to hide their PIN number as they type it in on the point of sale machine. These people usually do the same thing... they swipe their card, then when it pops up to enter the PIN, they'll partly look up to see me standing there, then cup their hand over the PIN pad and type away.
I'm sure they're just protecting their MILLIONS of dollars, right? Do they really think that I'm going to memorize their PIN number, somehow steal their debit card, then have a free-for-all down at the Walmart? Part of me wants to be insulted by this, and another part of me just wants to just laugh.
(For those of you who don't know, PIN = Personal Identification Number)
