At O'Brien Auto Performance in Tulsa, Oklahoma, kilt-wearing mechanics will fix your car while Celtic music plays in the background. Just be careful where you look:
David said wearing a kilt working on and under cars requires a certain kilt etiquette.
"Keep your knees down and your feet crossed, then everybody's happy and safe," O'Brien said.
He said they also need to be mindful of leather interiors on 100-degree days.
Especially if you wear a kilt "regimental style."
