How about people on here just quit being an A$$ to people they think are asking dumb questions. I was taught the only dumb question is the question you don't ask. Now granted, if someone comes on and has 10 dumb questions in a row and it's obvious they aren't putting any effort into trying to learn, then a harsh response might be necessary.
IF you think a question is dumb and doesn't deserve an answer, don't answer it, don't go all PCA on him by being rude. No one knows anyone else's circumstances or why they're asking what seemingly appears to be a question with an easy answer. Scott's situation is a perfect example. Sure, take a lug nut or the stud off the car and trip on down to the store, IF YOU HAVE THE CAR IN FRONT OF YOU.
I'm not going to apologize for any rudeness you given, the one who inflicted the rudeness upon you owes you that, and it appears he's eating up some crow pie right now. I will ask that you don't judge the rest of the group here based on that.
