Trade school drop out?

A number of years ago we had our pharmacy remodeled. We got all new fixtures, carpeting, etc. We even got a new sink. Now I'm no plumber, but it seems to me that the first step in removing and/or replacing a sink would be to turn off the water...... Unfortunately, the (supposedly qualified) plumber we hired forgot about that one tiny step. Fortunately the electrician who was working in the pharmacy that same night had turned off the power or we'd have had barbequed workmen in our new indoor swimming pool. It was quite awhile before the carpeting stopped going "squish" when we walked on it. What the f*ck is wrong with you?
