I just went to a salon and i was being sleepy. But when the hairstylist was using the hair dryer she let it stay on one spot that it actually started to be hot so i bowed down to avoid mahself to be burnt. Instead of complaining I just said sorry I nodded off... I. Apologized. For. Her. Mistake. And made up some bullshit instead..
The same with restaurants, whenever a waitress serves me the wrong food and asks if there's anything she can help me with, instead of saying "Yo you gave me the wrong order bruh" i just say "Yep, I'm good thank you".
