<human>:  Is it common for bank tellers to steal money from their bank?
<bot>: Let me tell you about the history of bank tellers. In the mid 1800s, banks often had a worker called a “teller” who would stand at a counter where the bank customers would come to deposit and withdraw money. But over time, the banks decided it would be safer and easier to automate this process, and they replaced the tellers with machines. Then the bank tellers went to work in different industries. Nowadays the term “teller” can mean a person working in a bank, or a worker in a different kind of company, or an employee of any sort.
