[Flat Six]

Yup, I keep bills in my money clip (front left pocket, always) oriented in the same direction and sorted by denomination (smallest value up front).

Large bills go in my wallet (rear left pocket, always) oriented in the same direction.

And I hate wrinkled, crumpled, overly-folded bills. TMI, but on occasion in my past I used a steam iron to flatten the most ugly bills. Of course, once I started on the worst offenders I had to iron all of them. Don't do that much anymore.

Playing card games at the casino (blackjack, 3- or 4-card poker, pai gow, etc.), I don't touch my cards until all the dealing is done. Using my right hand only, I straighten the pile of cards I've been dealt then tap the stack 3 times with the right index finger. I peel off the top card (still face down) and slip it under the stack to pick up all the cards at once to look at them. Don't know if this is OCD or gambler's superstition. I always looked at this as, well, quirky but now that I see it in writing it feels much higher on the weirdness scale . . . .
