Do attractive people recognize when someone is shutting down internally because of them?

I'm aware of how common this question might be, of course most people have felt it at least once. The 'Halo effect' or whatever.
But, the reason I ask this is because I'd gone somewhere to order breakfast. Some guy was running the counter and needed someone else to log in, and it ended up being some really pretty chick with a clear customer service tone.
I ended up ordering less food, couldn't glance her in the eyes, and just decided it was a surprise diet. I wasn't worried about being seen as a fat ass, I just wasn't mentally prepared to feel like I've been thrown back into high school and shut down under invisible pressure.
So, essentially, their company unintentionally made a little less money because of it, and it got me thinking about the potential drawbacks conventionally attractive people might face (in lieu of their many benefits)
Am I overthinking this? Maybe. But I'd rather overthink everything than never question anything.
