Nothing wrong with making a mistake. Good to see an apology too. They do have a great reputation.
I was a mechanic for 1000 years. The only people I ever talked to, were all fired up to begin with. I just had to touch it with a pin sometimes and it would blow up.. LOL I had a guy pass out one time. Turned RED and passed out.. I laughed the whole time. Everyone was relieved when they took him away. We fixed the drill and drank some kind of crazy drink from Panama. I woke up in the John, with the door locked huggin' a machete. Don't drink the water either..
Regards
