Ambidexterity

Unlike other countries, we Americans drive in the right hand side of the road. So the steering wheel is on the left. Which means the ATM you Neanderthals drive up to use to do all your banking is outside your driver's side window. 

So unless you sit backwards, then your left hand has to do the work at that ATM. So how come I have to watch the clown show every time I drive up, with the door opening, some idiot hanging halfway out and using their right hand. I'll tell you why...

Because your useless. Being able to use both hands is a quality that sets us apart. Now, nobody is saying you have to write with both hands, or throw a fastball, or even high five. But not being able to lean a little, tap that PIN with the old southpaw and make a simple transaction should be ez. But you can't. Useless.
