I have never worked as a barista, but I have worked as a line cook. It's not hard to cook one thing. It takes some time and practice to cook many things at once at a speed that keeps up with a good lunch rush. You can also easily compound the situation by trying to go too fast anyway, resulting in orders being sent back.
Yeah it’s like juggling. A non juggling person can’t really just decide they’re going to juggle a few hours a month and expect some balls won’t be dropped.
Yes. About the least-skilled position in retail is working the POS. Even with a touch screen, it takes practice. It makes a big difference if the operator knows where all the buttons are as opposed to having to hunt and peck. Yes, the machine tells you how much change to make, but picking up the right number of coins by touch instead of by picking up a bunch of them and counting them out into the other hand, that makes a difference. Picking up single bills out of the cash tray without fumbling takes some touch. Knowing all the sizes (short, tall, grande, venti, trenta?) and all the drinks. If you are at a store where they don't print drink labels, you have to know the order in which to announce a drink (size, modifiers, drink-type, but make sure the modifiers are in the right order) and the shorthand for the sharpie markup of the cups.
There's skills you need. None of it is that hard. But it is not easy to do it at speed without practice.
Yes, working as a barista means you're running multiple independent instruction loops in your head at all times, while also having to act like a pleasant sociable human.
