My DH has just started a gardening business, which includes cutting grass. He's been to three houses in the last couple of weeks where he's not been able to cut all the grass due to dog poo all over the place. The clients have all known he was coming, but appear to not have made any effort to clean up the garden before he goes. Today he's had a complaint that he didn't cut all the grass (he'd cut 2/3 of the grass before he realised the bottom 1/3 of the garden was very messy). He sent a very polite message after his visit to explain why he hadn't done it all.
Is he BU to not clean up this mess/cut this grass? He doesn't want to offer a cleaning service.
