Useless Advice

I would have to say that the most useless advice I have ever been given was when someone tried telling me how to jump a diesel truck. the funny thing is that the guy apparently forgot that i do that at work probably 5 times per week so most likely i know what i am doing. Another funny thing is that this guy told me to connect 2 sets of  jumper cables and they aren't even big gauge wire so they will loose amps very fast since the bigger the wire the more amps they can hold. then they guy told me i could start it now well the next problem is that a diesel needs 2 batteries and there is only enough power for 1 battery... needless to say i did it my way and got is started first time and proved that guy completely wrong. I hope that he learned that he is a idiot and does not know anything about what he is trying to tell me what to do.
