ive always just mimicked things like that, if I’m doing it also it doesn’t drive me crazy and may get them to stop
I did a couple times. Sometimes harder. It wasn't easy though. The height was just awkward enough, especially with boots on, that it wasn't nearly as easy for my height as it is say, right now sitting in my work chair. But in general, I'm with ya, I usually will mimic them, but only ramp it up a notch or I'll say something if it's more egregious (like take your phone off fucking speaker).
It was a Sunday morning, so it was slammed. Servers, the cook, the counter guy, the hostess....every one kept stopping by to chat with this guy. They'd comment on how busy they were. Hey, fuckheads....you ARE busy. Stop socializing with a guy you're going to see at 6pm, which every one of them discussed. For a guy who is in the business (he worked elsewhere), you'd think they'd have the sense to not come in at rush hour and disrupt basically every employee for his entire time there.
And even worse, he was one of the worst personality types to have to listen to. The people who laugh at EVERYTHING. Everything he said, he laughed at himself. Everything they replied with, he laughed. Most of this was not funny conversation, they were "how ya doing" and talking about meeting up later. Why the fuck was he laughing....it was a stoned laugh either, it was a Neil DeGrasse Tyson "I love to hear myself talk" laugh.
