One of my new customers (very first mow!) called about an hour after I left her property this morning. She said I broke a rear bedroom window. I swung back by her house and inspected the window. Definitely broken. I did not admit any guilt, but told her the first step would be to get an estimate and call me. Advice needed: Did I act correctly? If not, what should I have done? Also, what is my best course of action when she calls with the estimate? I am starting my second season and did not have an incident like this last year. Thanks in advance.
