1. When judges solve during your solve (or a special case where my judge was reassembling a 3x3 and it exploded over the entire station lol).
2. People asking to see your cube then instantly dropping it as though they've never held a 3D object.
3. Non-cubers going out of their way to prove that cubing is actually just an illusion that requires no skill regardless of how much you explain the actual process. Like one time someone watched me solve a 5x5 amd said things throughout my entire solve like "No no no he's doing the exact same moves over and over again" (I most certainly was not). Bro FIRMLY did not believe that different scrambles had different solutions.
4. My cubes exiting the scrambling station covered in grease or feeling like a completely different puzzle.
5. People screaming when they get a good time(or sometimes a bad time for them) next to you (I totally get being excited and celebrating, but I have issues with sudden loud noises right next to me). If I know I'm next to someone who frequently does that, I wait until they're finished to begin inspection.
6. 3x3 OH
