Checking receipts is extremely important, says former cashier – especially on Mondays. Expensive mistakes can creep in, especially at the beginning of the week.

For example, if you pay the price per kilo for an imported mango instead of an Annabelle potato, it can be expensive. It is also in the interest of the cashier to have the right amount of money in the cash register at the end of the day - neither too little nor too much. Complaining about incorrect prices is difficult in some cases.
