I am 21M and I work at a barbershop.

One of my university professor's has recently started coming in.

I've seen him three times now and although up until recently he has never been my client, I sometimes had to shampoo his hair and stuff.

I always try to keep conversation with him to a minimum, even though he is always trying to engage me. The reason I keep my distance is because he made what I feel was an inappropriate comment to me in the past.

During a previous semester, I was his student for one class. He requested I meet with him during his office hours to discuss an exposition in which I'd shared my personal experience with depression following a profound loss of a close family member. I won't get into the details of that but I'll quote his problematic comment best as I remember it: 'You're not depressed, You’re just a moody bisexual who is having trouble admitting to himself that he may just be gay'. He also graded me unfairly.

I was so shocked by his comment because no where in any of my submissions or during class had I ever talked about my sexuality (being bi). Instead, this is something I learned he put together from looking me up online. He admit to having come across my TikTok account and he must have done a very thorough deep dive because he found a comment reply I'd made where I had said I was bi. I don't even remember the comment and it took me over 20+minutes of sifting to find it. I was mostly active on Tiktok during the pandemic when I was bored. Long story short: a bunch of my stupid TikToks became popular to some extent and attracted flirty comments.. some of which I replied to.

He played it off as it being public information and that I should be more private about what I put out there if I'm so concerned. He mentioned he looks up his students often, and that future employers will do the same. I didn't want to argue off topic so I dropped it, leaving the conversation at 'I disagree with you and I'm submitting an appeal'. I initiated a review, got the grade I deserve and moved on.

Back at the barbershop, he requested my boss to switch him over to me as a client. I told my boss privately that I would like to refuse him as my client.

My boss didn't think my reasoning was valid; I ended up having to provide the service.

During the service, I was calm, detached and professional. I didn't talk other than about the service I was providing. He tried to make conversation outside of that and I ignored it. I told my boss I'm not taking him as a client in the future. My boss thinks I should let it go. AITAH for not wanting to provide a service to him? I can't explain it, but this man makes me very uncomfortable. I know it's probably just a coincidence but I hate that he's found his way to where I work.
