I'm going to skip the line for an order
Why are you going to skip the line?
I have been waiting in line too long and I'm ready to go now.
Skipping lines is rude to others who have been waiting. You need to be courteous to other people and wait your turn.
I don't care.
You should care. Other people will be annoyed with you because you are being rude. They've waited as long as you have or even longer so what gives you the right to be rude to them?
