6. Cashier
When we say “finance” we mean money, don’t we? But, nowadays, banks do not work with a lot of cash, so tasks given to cashiers are actually limited to some small payments and billing in cash. However, it is a highly responsible job since any disagreement in the bills and the amounts of money leads to being fired or even sued and possibly taken to prison. If you choose a job like this, knowing a lot about finance is not necessary, but you need to be good at maths and be very patient with your clients.
