Pros
Being a cashier can be an attractive position for people who enjoy interacting with the public. In addition to engaging in conversation with customers while ringing up their purchases, cashiers serve in a customer service capacity by answering questions and helping resolve complaints. During busy periods, cashiers often experience a steady flow of customers through their line, which can make the workday move quickly.
Kontras
Complains more about the customers than anything else. Pay is better than nothing. I think anyone can have a job and make it into a good or bad thing you can never expect someone else's story to match everyone's story. Different stores have different managers/people/employees so what you may find true in one store you may find it not to be true in another.
