I don't know much about computers and have no skilled cashier experience. Can I apply for a hotel cashier?

You don't need to be proficient in computers to be a cashier. You just need to be able to operate it simply. You can communicate and learn with people who know computers around you. Computer operation is not difficult, it will be easier to operate more. After all, computer is also a basic skill, which will benefit you for life and help you in your future work and life. If you want to learn computer knowledge systematically, you should go to a professional school. I hope to adopt it, thank you ~
