I'm with you guys on the ordering bills (though not to the extent that Bede does it) and the refusing to take the first item (like miss p said).
I also have a weird ordering compulsion. Aside from just alphabetical and numerical ordering, I have to have things lined up on my desk or table. For example, at dinner, I'll make sure my knives and forks are lined up with the plate or placemat, and also that the cup is centered or lined up with any patterns on the table cloth, etc.
And at stores, while taking the item not immediately on the front of the shelves, I will pull the remaining items behind it forward. Must be my Target team member training.
