yes i have this too im an ironworker and a lot of the time im told to go a specific thing like weld on these clips without an explanation on why i need to do it    if i have a better understanding of what its purpose then i can catch mistakes that i might be doing when welding them in like they need to be a certain way so another trade can get their stuff in this same spot or because later we are installing something else here that uses these clips so its better to not make it super tight against the ceiling to make more room to help get the piece in     when i ask a foreman why were doing it i get talked to like im a total idiot but unless i know why im doing it i wont remember all the details needed to do a good job   thanks for posting i totally relate
