Well, it could be, that they were a little upset. It depends on what they said beforehand: Options
1.) "No, we don't tape & paint grooves, the outcome will not represent our shop's quality." --> paint job rejected
2.) "We have to warn you, we won't be held responsible for the result, if you insist on us doing the job" --> paint job rejected at first = Will be upset, no way of doing it better, if you insinst on the bottom line
3.) "Sure, no problem" --> A re-redo for free
I would take a black marker, run around the grooves and job done
okay, and if that fails, I would ask them what they were thinking
