She called for me to check the system because it was coming on when it's not supposed to and grass is brown. First thing I notice is controller off time and at default settings, 10 min a zone every day. I check all zones and all heads and reprogram controller. I billed her 75.00 What would you charge? It's not like I was next door, at least 20 min drive time one way. Long time customer and an old system I didn't install. I almost called her back when I was hot and tired and tear up the invoice and find someone else.
