We took an informal poll at WalletGear and asked our visitors if all their bills in their wallet have to face the same direction.
We learned some people will organize each set of bills according to value (1's, 5's, 10's, etc) and face the same direction. Some say this method wouldn't save them time, but others have been doing it this way their whole life and wouldn't change.
So how many people organize their bills this way? 82% of people polled versus 18% who do not organize their bills this way.
Obsessive compulsiveness showing through? Maybe, but definitely, it turns out, something most people like to do.
