Customer called me to see if I could fit a semi-annual kitchen fire system inspection in. I was already heading his way and said I would be there in an hour. I arrived and inspected the Ansul system thoroughly. I did not find any defects or deficiencies. I completed the testing and put the system back in working order. I did do some repairs and now the system is code compliant. I wrote the report and told the owner that I would send a bill.
