I work at the customer service desk of a grocery store, so that probably "fits" my type. I like it well enough, and the people there like me. Customers have even told me I'm the nicest person they've ever seen working at the desk. I've also been told that I sound like an automated message over the intercom and that people can always tell that it's me because I "sound so sweet".
Although. most of my work in customer service is western union/money orders/returns/getting people their cigarettes. Occasionally helping people find things. Answering the phone and directing calls. Printing out the hourly sales every hour on the hour (I have to watch the clock for this). And when they're down cashiers, and there's more than one person who knows how to runt he desk there, they'll put me on a register since I am also cashier trained. I've worked there for two months now. I like it, but my hours are a little unpredictable and, like all minimum wage jobs, they can't schedule more than a few days in advance because of a high turnover rate. If I stick with them long enough, though, I'll get raises. A girl who's worked there a few years is already up to $14/hr. Where I am, minimum wage is $8.05/hr.
Before my current job, when I was still in (community) college, I worked during my last semester as a supplemental instructor for PHI 103 (philosophy of logic). Absolutely LOVED the subject, and the teacher (the only logic teacher at that store--he was my teacher and after I took the class I got to work with him, which was great). I held help sessions for struggling students, and many of them were extremely grateful and claimed they wouldn't have passed the class without my help. I made a couple friends along the way, even. It paid better than my current job, but capped your hours to only 10 per week maximum. And you have to be a student to work there, so after I graduated I had to leave, otherwise I think I'd have stayed there. I thought that job fit me really well, since it's people-centered.
My very, VERY first job was McDonalds. Hated it. Management sucked. Customers were rude. Coincidentally, it is RIGHT next to the grocery store I now work at... and even though they're so close together, no one is mean to me at my new job, whereas almost all customers were rude to me at McDonalds! Probably because hungry people get pissy. My ISTJ best friend (still going to college) still works there. I like to visit him after work and leave notes on his car. But back on topic, I was a good employee at McDonalds for as long as I was there. I was amazing at headset and backbooth, and of course most of the time did both simultaneously as most places do to "cut back on labor". I did handout a few times. The job stressed me out a lot because of the fast-paced environment. Working like that, I could DO it but the stress wasn't worth it. Especially not for that pay & putting up with that treatment from customers & management alike. Glad I'm gone. ISTJ friend has worked there longer than 98% of the staff still working there and only stays because he's afraid he can't find another job since he's in school right now.
tl;dr I think customer service/people-centered jobs is a good fit for my type but fast-paced ones are really stressful.
