My biggest pet peeve was working in a restaurant and trying to seat a large group. That hatred has been with me for decades, that I actively refuse to involve myself in dinners larger than 6 people. It’s noisy. It’s too much management. There’s multiple conversations. It’s awful.
Even during family outings in public areas, I assemble little groups and pretend like we don’t know each other.
And before anybody even asks, I absolutely segmented my wedding into different 6-person teams when we went out in public.
