No, and kids these days are awful, like really, really bad. Look, I get it, you accidentally opened the drawer without putting in the amount the customer gave you and now you’re flustered or have tunnel vision, or worse, the customer is telling you how much the change is*. Kids (mine is in public school, common core and all) are taught how to make change in grade school, but it’s almost like they need to be retaught in high school. Making change is different than regular arithmetic. If for no other reason you have to do it in your head and, personally, I hate that counting backwards in your head stuff. There are better ways, at least for me. I grew up running a register and when I got the money from the customer I would try to come up with the change before the register told me. I got very good at it.
On the one hand, I’m not that surprised when I see one of my high school employees doing $20.00-$13.77, with a line of customers and trying to make sure she’s going it right after a lifetime of ‘when are we going to need this in real life’.
On the other hand, I’ve seen, first hand, my employees using their calculator to figure out their 50% discount on food. No line, no pressure, literally doing $1.99 divided by 2, 99¢ divided by 2 etc. I don’t know the odd (as opposed to even) was throwing them of if they’re just that reliant on a calculator. I’ve walked by, in those cases and said, uhhh that’s a dollar, that’s 50 cents.
Oh and in the first case if I see them with the calculator and see a 20 dollar bill out and $13.87 and say 'hold up it’s 6…20…3, yup the change is $6.23, I’ll get a ‘how’d you do that’ from them and I’m like ‘uh, aren’t you the one in high school?’. The few times (post college) people have said ‘well, that’s because you’re a math major’ my normal response is something along the lines of ‘yeah, but I didn’t spend 4 years doing arithmetic, you’re en English major but you didn’t memorize the dictionary, right?’.
Regarding the Bush thing, what you said is probably true, but some people also don’t know the prices of stuff they buy on such a regular basis. I mean, if he didn’t know if it was a dollar or twelve dollars, yeah, that’s one thing, but if he didn’t know if it was $1.99 or $4.99 that’s different. I buy, for example, sour cream every week. I’m not price shopping, I almost always get it from the same store, it is what it is, I don’t even look at the price.
TL;DR, kids learn, but many can’t do when put into real world situations with a bit of pressure on them.
