1. You never know who you will meet.
Each person has their own unique story. You get to talk with all sorts of people from all walks of life. You meet people who have survived war or sickness, who have traveled to all parts of the world, who are fluent in multiple languages, or who were childhood friends with your grandparents. You have the chance to learn and grow from hearing of others experiences and by sharing your own.
2. You learn patience.
Believe it or not, every person isn't walking around having a ray-of-sunshine kind of day. You'll have customers and clients who are in a bad mood, dissatisfied for whatever reason, or just looking to argue. When you encounter these people, you may want to scream at them, give them a "piece of your mind," and kick them out the door. However, you cannot do that. Your boss is going to want all the business you guys can get. More money makes everyone happy. So, you have to be patient with the clients and customers, show them kindness even if it isn't shown to you, and try to help them in anyway you can.
3. No two days are alike.
Each day is open to endless opportunities. There are often multiple tasks to be done, some you may be rather experienced in and others could be brand new. There are many people who could walk through the front doors of the establishment, some may be regulars and others delightfully new strangers. Each day is a new day to make uniquely your own.
4. You can make a difference.
Whether it be in the life of one individual or an entire town, you have the chance to make an impact. Whether it be the words you say, your actions, or the love in your smile, you have an opportunity to impact each person you encounter.
5. You can become a valued part of the community.
The part you take, no matter how big or small, is needed. You can be a part of a huge system that makes life happen. Your job matters, whether one person, or a hundred people, or thousands of people are depending on you, your job matters. Without you and what you contribute, your community would be entirely different.
Every person should, at least once, work in and with the public. It can change your entire outlook on life and open you up to experiences you never thought you'd have. I've benefited exponentially from it so far.
