You should keep this job.
This will seriously make for job interview conversation when you're leaving college. Employers are going to ask you questions about it basically because it's an unusual job. You can tell the stories, just like you did in the OP, as solid examples of how you're able to think on your feet, work with demanding customers, etc. Basically, graduating college students are mutants anymore. They don't know how to communicate in any way, shape, or form, and I personally cannot stand to deal with that. I'm only 27, but I feel like things took a nosedive while my peers and I were in college.
AIM and email took over as predominant forms of communication, so people younger than me don't consider picking up the phone anymore in a business matter. Written communication is awful to quite awful. If I get a guy who had decent grades but a job like yours that required some thought to keep the energy going with a crowd, I'm going to seriously consider hiring him. You can spin a lot of what you're doing into transferrable skills if you go on to graduate and do anything that involves working with other people.
Look, I'm a management and tech consultant right now, and 75% of my job is actually figuring out what different groups of stakeholders want, get them to play nice with each other, build consensus, etc. And this is with a major consulting firm, the kind that hires 4.0 students out of undergrad business programs and the like. Our entire job is keeping the client happy and delivering what they want, and most of the client base is from a more senior generation that still wants to pick up the phone to ask a question, expect decent form in an email, and overall professionalism.
If you can succeed in keeping your current customers happy, future employers will look at this as proof, as long as you spin it as transferrable experience. Sorry for the mini-rant, but the issues you're going through with this "meaningless" (in the grand scheme) part-time job are more important to your professional development than you think.
