Answer me Ska_man, why Autozone loans tools for free? Does it bring them profit? Yes I and many others go to Autozone to get pullers, stretchers all kinda tools that occasionally needed(not always) to use. I and many others buy and return equipment from BestBuy monthly, daily, hourly and every minute, second. What'd'ya think? Can you do the math?? Can you find what's wrong in your statement by solving elementary school equation?
Apperently you definitely need to find some learning resources about profit and return on investment before making such infantile conclusion that really make me look like I'm an idiot and so be it because probably I've got used to it.
After attending some PTA meetings as one of the examples, I found out that teachers of elementery school don't know who is Mark Twain, Alexandre Dumas, Homer; also found science and math handouts with obvious typos such as kg/s units of force. What really shocked me, that most of parents and teachers didn't know what I was talking about exactly like both of you and many others of a kind.
Consider me agreed on your and Liz's statement 100%. YOU WIN.
P.S. Following idiot's advice is truely optional and not obligational...
