Hmmm… don’t know about shoes or socks (I don’t seem to have a preference).
As for picking up pennies, I always do so. If it’s heads, it goes in my left pocket into my pocket change. If it’s tails, it goes into my right pocket, and I pass it along to a server (the bad luck never transfers, or so my mother told me).
Does sleeping standing up count as a quirk?
