Is Self Check-Out Really Faster?

For an impatient geek there is nothing…NOTHING more annoying than standing behind someone in a grocery store that has the audacity to write a check in the 21st century. That is why I head for the self-checkout lines.


Generally, only those brave enough to tackle the machine and handle the pressure of nerds staring them down choose this option (athough I have seen people use checks in self-checkout-the ultimate horror). Even when I have quite a few purchases, I would rather scan it myself and avoid any unnecessary human interaction. But what about you? Do you prefer self-checkout over manned registers?
