How many different ways can you ask the same question? Tools belong on a bench, on a belt or in a vehicle...not in someone else's drawers. When it comes to tools and other people's drawers, you need to ask permission...and yes...it is supposed read just the way it sounds!

To play the devil's advocate what type of tools are we talking about ? Something light like a screwdriver in where no scratching can occur or something heavier like a circular saw and/or its blades ?

Small things but some drawers were pretty filled up

My suggestion: After contractor has left for the day, empty all the drawers into a box...or three and leave the box in the middle of the floor when s/he comes back...remove the drawers and hide them...this should be enough to let the person know this is NOT acceptable to you.

Their reaction should be quiet embarrassment. Anything else is inappropriate and would lead me to believe you need to hire someone else.

OP, why 4 threads asking the same thing?

I personally don't understand what the big deal is, but if it bothers you then sit down and have an adult conversation.
