That's completely valid and I can agree with you there. I get nervous too when I feel people shaking a booth. Seeing other people fidget in general can set me off, and I generally don't like to eat in public either. What prompted me to comment was when you said: "A grown adult and you can't sit still in a restaurant like a grown up without shaking your leg". Adults who fidget in public usually can't help it and/or they don't realize they're doing it, and they're often already struggling with negative stigma. Like, you can be annoyed about something without shaming people
