I haven't worked retail since college, but when I did, we had regulars who came in, spent a ton of money, and we prioritized their experience.
Always. And this was everywhere I worked, from the local bookstore to Nordstrom. And to this day, when I'm shopping, sometimes I get bumped for the regular (and sometimes I'm the regular they prioritize).
Are you sure you want a customer service job? It doesn't really sound like it. Trust me, it's not the type of job where you can act like you're doing them the favor.
Is there a program you could do that would allow you to get the skills you need for something that would excite you more?
