Help me not be a pushover

[MadamePresident]

Help me not to be a pushover. My deck, patio, retaining wall project is supposed to be done today. There are a few corrections to be done or things that look like they were done sloppy. I generally expect the best of people and I feel weird telling someone who is an "expert" that they did things wrong in an area where I am inexperienced.

I already went out this morning to talk to the foreman about 2 boards. He didn't have any extra with him and was just like "if it becomes a problem we can fix it". I think it's already a problem.
The other one he brushed off my concerns.

I'm kind of apprehensive since I'm supposed to sign off on it later today. Usually my husband handles this type of thing and I don't want to approve something wrong.
