Count change immediately
I watch it over and over again while shopping: the receipt is controlled by some, but the change that the cashier releases, usually in the purse, instead of being counted immediately. Maybe because the situation at the cash register is stressful anyway, the next customer is already waiting and you want to get there quickly.
But you should definitely get used to this. Because how often are 20 cents and 50 cents confused, not even with malicious intent. Once the money in your wallet, you can not understand it. Therefore for safety's sake, always recount the change immediately!
