Alright, there has been lots of talk about bashing, and bagging on other trades. May be it's time for some of us to come clean...
I'll start....
Once went through a 1" gas line with a 2" hole saw, after checking under the floor apparentley not well enough.
Drilled into the building next door with a 6' flexible bit.
Knicked walls with ladders, and tools.
Scratched floors.
Broken mirrors by over tightening fixtures to them.
Missed outlets and switches.
Out-right lied to inspectors...
Anyone else....
