If you don't have direct experience, try to study the important aspects of cashier-type duties to be able to speak to your ability to handle this part of the job.
"As you can see from my resume, I worked as a cashier during my final year of high school. Cashier duties required a strict attention to detail when accepting cash transactions and counting change back to customers. I also was trained to follow guidelines when accepting written checks and testing large bills for counterfeiting. A lot of transactions were also handled by credit or debit cards and I had to help customers work the self service pad for transactions. At the end of each shift, I was responsible for balancing the cash and checks in my till against the transaction registered. During my time on this job, I never had an issue with an imbalance at the end of a shift."
