Since when? This isn't even relatable at all. Idc if I need to get up right when someone else just got up before me. I just don't understand how you'd think it's awkward to stand up while someone else is standing up to go do smth.
Me, an overthinker when someone stands up from their seat to go do something RIGHT before me (now I have to wait another 4 minutes before I can stand up, for it would be awkward if I stood up right after them):
