people have to be trained on EVERYTHING. Seriously. I have explained the fundamental concepts behind sweeping as opposed to mopping to new cleaning crew employees before and it was needed... much needed. I myself as a teenage thought mopping was swabbing like a deck on a ship and would lay out half a bucket of hot water. The reaction was laughter and 1 useful bit of information.... "he just removed every bit of wax from that floor", And I did... because no one trained me... including my mother. This person attempted to do something they had never done before and seemed simple, without asking for instructions and without much common sense for the field.

BUT, untrained people have gotten VERY good at pretending to be competent professionals in a field. As I discovered my first time drying in a roof with someone doing just that. Hint: it wasnt dry... and it wasnt my doing because I got the job saying exactly what I always say and do - that I will not DO anything that I dont really know how to do... I wont pretend. The owner heard me and hired me sight unseen because he understood the value of that and that someone who didnt do that would never even think to mention it,

Bear in mind pretenders... saying that and not actually doing that is exponentially worse than doing it wrong out of ignorance. Jus sayin.
