Totally agree. Too bad that human nature plays such a role in placing doubts on your professionalism and intentions. Unfortunately, I have found too many GC job site supervisors suspicious by nature. I'm sure many have been burned and even fired over things out of their control (like concrete drying). Installers are much better off bringing in the independent testing agency to test and be the bearer of bad news rather than appearing uncooperative with the GC and risking future installation business!
