Reminds me of this time we had a similar rule for securing gear before a big storm. The foreman was SO adamant about double-checking everything, and it actually saved our setup when winds picked up. That kind of discipline just STICKS with you after a close call.
Mistakes under pressure really do show you who knows their stuff. That wrong call on the line can freeze a whole site, but getting through it makes a crew tight. You learn more from one real mess than a month of things going right. It's those shaky moments that build real trust, not the easy days.
