You want to know something that irks me every time I encounter it?

When I am at a cash register, and I am using a debit card, and I have to run through the rigamarole of learning how this specific card reader works because they just can’t all work the same way. It’s like “Ok, pin number… check, no cash back, correct amount, done. Oh no wait. It wants my zip code.” or, “Ok, pin number, no cash ba— er, no, I mean, yes, that is the correct amount, oh now no cash back; what the? Yes, that is now, still, the same correct amount. What? Show card to cashier? She already approved. Kajhfkas askjdhajshd asjasd.”

What drives me up the wall even more though — is when it says something like this:

Select the amount of cash back you would like:
[$20] [$40] [$60] [Other] [No]

This always trips me up, because I don’t want cash back but for some reason my brain will not automatically recognize “no” as an amount. And that reason is because “no” is not an amount. “None” is an amount (or a non-amount, (look, just leave it)). I just stare for like, five whole seconds with nothing but the Hypno-Toad sound in my head. And then I suddenly get it, and am like “Gahhh! NO, NO, NO, NO, NO!” Jabbing it with my finger. This does not work however, as I have to use the stylus, on this card reader.
