another plumber sidled up to me today and commented that he understood I told his customer to go forth an procreate on the phone after they asked for a written quote to fit a cooker hose, he said I wouldnt have much work if I carried on like that. From memory it was a telephone call at 9:30 on a saturday evening and they wanted the job done on the tuesday after they had seen a written quote, seems they caught me at a bad moment 🙂
I'd be giving him the same advice 🙂
