I know, especially in America, where there are no sales apprenticeships.
I'm used to German sales clerks and waitstaff "counting back change" (and I was taught to do this, as well), but Americans will usually just hand me money, "Here you go." 🙈
This "one neat trick" is arguably the reason why Germany still runs on cash.
Another thing the American clerks typically do is put the money you gave them in the till or the wallet and then take out the return money. 🤦♀️ Then nobody can remember how much you gave and it turns into an argument about how much change it should be.
This is a fairly new phenomenom in the USA. It used to be that there was an expectation of service from vendors, and cash was king. If vendors did not live up to expectation word of mouth spread and stores/businesses died. Today people just don't care. They want digital fiat. They don't know how to count or expect anyone to do so becuase 'math is racist' and you don't want to be called racist rite?
The level of how bad this is depends on population and location... In most places now there are soo many people lining up to buy stuff from big box and low quality vendors that these vendors can offend 50% of their customers and not loose any sales becuase there is a line of customers out the door anyway.
