I always get ignored at shops, restaurants, friend circles, any suggestions to help me out?

Ever since I came back to my college after the pandemic, every time I went to college cafeteria I always got ignored by the shopkeepers there, and whenever I went to any restaurant nearby, I got ignored. Could this happen to someone who's ugly, and if it is because of that, could you suggest ways to get over it.
