I'm going to 'cut the line' at a gas station
Why are you going to cut the line at a gas station?
I really hate waiting in line.
It's normal to hate waiting, but you shouldn't cut in line at the gas station or anywhere else. Cutting in line is disrespectful to the people who are already in line. You should try to be patient.
Fuck that, I want to go first.
You are being selfish by doing that, if you wait instead you can avoid making enemies or getting kicked out of an area and not getting that service at all.
