As someone who has worked in the customer service industry... I will not allow you to belittle yourself.

What I do by no means [is] important,

If I were standing next to you right now, I would playfully but with meaning, open up your cranium, lean down, sternly point, and talk to your brain with the following. "You stop being mean to @magnetosphere@kbin.social or you're going to have to deal with me."

I 1000% disagree with the selected statement above. You and your work are very important to the people that come in. If it weren't for the work that you do, I can guarantee you that there would be more people feeling lonely, discontent, or frustration. Being pleasant is a sought after characteristic, I would argue in all work industries. (Think about it. How well would a company perform or last, if it wasn't for those who work there, being pleasant to be around?) Being helpful: I'm goodness. People LOVE to be out shopping and find an employee that actually wants to help you out. It's a high ranking frustration for customers in any industry. Nobody (in my experience,) wants to always have to find things or do things for themselves at a business. So if you genuinely like making people smile or providing a good shopping experience, you're a badass in my book.
