My boss has been calling this builder we've been working with for years, one of the few builders still giving us work, by the wrong name for as long as we've been working with him. He's butchering the first name, and calling him by the wrong last name, which is actually the name of the building company. Should I tell him he's been fucking up for 4 years? Should I ask the builder if he wants me to correct FH? Or just let FH continue to look like an ass?
