I’m just a regular. The point is I’m not signaling anything, I’m just not bothering with a signal because I have other things (namely, being recognized) that will e.g. ensure I get a table even if it’s a busy night.

If I go to Vegas I may grab a silk shirt because, yes, my service experience absolutely varies based on that, and I don’t want to have to wait until they see what I order or get to the check-in counter to start being paid attention to. (Which is annoying. And I prefer my t-shirts with cat holes in them. But I don’t like waiting in lines more than I dislike having to do my hair.)

(I do maybe counter signal in Palo Alto, where I refuse to wear a blazer or a Palo-Alto-grey hoodie. But that’s less of a power move than me inviting attention as a now outsider.)
