'Trust me, just do it': Contractor scores $12,000 extra on a job because a know-it-all client insists his measurements are accurate; they are not

Clients lie. This is the one thing that is certain for every contractor in every industry. For some reason, know-it-all clients feel like it's some kind of flex to press their hobby knowledge on someone who is literally a professional in that field. In this case, a pushy Californian client was getting his home remodeled and couldn't fight his manly urge to try and teach his contractor a thing or two about construction. Naturally, this backfired immediately and he was quickly in deep trouble with his wife and his bank account. 

The contractor, being the pro that he was, insisted on taking his own measurements of a particularly specialized arch project in their garage. OP wanted to come take a look for himself to make sure the add-on to the arch would be substantial enough for their RV to drive into the garage, but the client arrogantly pushed for OP to use his DIy measurements. When the original estimates turned out to be insufficient, and after OP had already charged the client, it was time for the client to reach deeper into his wallet to fork out the dough necessary to correct his monumental measurement– totaling $12,000 for a custom arch that could have been $4,000.
