Drummond is black. I'm not one for political correctness, but there is pretty conclusive evidence that a lot of non-blacks people think black people give off creepy vibes. The in-group favoritism bias is a very real thing and it is very reasonable that it manifests as a vague unsubstantiated feeling.
Somebody saying they ran into him at a coffee shop and got what amounts to a feeling of bad vibes is literally not evidence or conformation of anything about the man's character. It is quite likely to be run of the mill background racism. We know nothing about the commentator, nothing about the situation. And it looks like the standard outcome of racism. Even if it isn't the commentator can do a lot better than that with minimal effort. Now if there were any evidence of any kind proffered that would be a different story. You are fabricating some notion of some sort of 'active ... disdain' here that isn't mentioned in the objectionable comment. If they don't mean unsubstantiated they shouldn't be saying unsubstantiated. They should be substantiating their claim.

There's pretty conclusive evidence that a lot of people think 'people outside their in-group' give off creepy vibes, yes. It's not a black vs. non-black thing, it's literally that being together with 'familiar' groups of people makes you feel more comfortable than otherwise. And while this can be a source of unwanted 'noise', it can also be quite separate from the more specific feeling about a particular person's attitude. I'm pretty sure that if we asked OP about black males other than this guy, he/she would tell us that no, as a rule, they did not make him/her feel uncomfortable the way he did.
(After all, working at a firm like Google, in this day and age, involves being exposed to people of many diverse backgrounds and being willing to engage with them as peers regardless of how one might initially feel about their group identity. That's a pretty good antidote to ingroup biases!)
I did mention disdain as a possibility because that's perhaps the most common source of those "inexplicable" creeper vibes, and also because OP themselves seems to be drawing a contrast between these and the "friendly" attitude of the person they worked with.

The standard should be higher than that comment.
