Thanks Brett & Kiwi

I was all theory and absolutely no practical for walk ways or escalators. Strangely I've only ever helped other mechanic when they need a pair of hands and no one else was available.

Greenpants, I get those comments too! They are not as funny as they seem to think they are. But I politely acknowledge their attempt at humor. I've certainly fell short on many attempts. What I would like would be an arsenal of witty responses!
