I'll try to be succinct, here, but it's a bit long:
I used to be a dealer in a casino. Dealers are required to 'wash their hands' (clap together, then flip palm up, and then palm down) so that the eye in the sky (overhead cameras) can see we aren't palming anything. We have to do this anytime we touch just about anything atypical to dealing, and when we are replaced by someone else at the table.
I haven't been a dealer in many years, and yet I still 'wash my hands' reflexively in various situations. Including hitting snooze on the alarm clock, or anything else I do while I'm half-asleep still. Hit snooze. Expose both hands. Clap together, then with one hand palm up and the other hand palm down, flip them to expose both sides. Then crawl back under the covers.
Oh, don't apologize for laughing - It's funny! I know it's silly but, hey, I can't help it, so might as well get a laugh out if it, yeah?
Of course, doing this while wide awake is when it gets embarrassing. Like in a grocery store... taking something off the shelf, putting it back on the shelf, and quickly flipping the hand used in this action palm up/palm down to show it's clear.
At least now I am able to actually accept cash placed into my hand, instead of asking the cashier to put it down so that I can pick it up (we weren't allowed to have money placed directly into our hands at the casino). So, hey, progress!
