It's always a bit awkward when I'm making a purchase, and decide to use some of the copious coinage usually present in my pocket, such that the change
is only one or two cents. I can't bring myself to simply walk away while the cashier is getting it ready--it seems like a violation of the procedure,
and might catch them by surprise, or worse cause them to call after me, so that I'm going to even more effort than I otherwise would to get my
pittance. There's also sometimes the matter of the receipt, although in most of these transactions (the greatest portion being when I'm buying candy)
that's even less important to me than the pennies. But I also don't want to look like I really care about the change. So I tend to try to look busy
or nonchalant (an ability I lack entirely), or even take a step toward the exit, and then simply put my hand out for the cashier's offered fist, as if
I don't even know what I'm getting. But who am I fooling: I already used some coins to pay, so I know exactly what's coming. For those thinking I
should just say "keep the change," forget it, way too condescending coming out of my mouth.

Ah, excruciating minutiae.
