It’s where you make or break you reputation. Blow them off and you’ll work yourself right out of town. Send your lowest paid guy to do the repair and you’ll be dealing with it again. The only approach, you suck it up and send your best guy to get it fixed right and move on. Yea, you’re losing money either way but your name is all you have. We all make mistakes but admitting them and owning up to it is what will build long term success, even if it doesn’t feel like it on one particular day.
