Stumac....... when a customer asks how long a job will take, if i am not too sure i tell them that i will leave x amount of days in my diary for this job. so if i think a job will take me 3 days but i want to cover my arse, i tell them i will leave 5 days free in my diary, i explain that i think i'm sure i can di it in 3 but just incase something comes up i will leave 5 days booked especially for them so i am not in a possition where i feel i have to rush and this is how i manage to always produce beautifull results!!
I also explain that the price is for the job and if it takes me longer than i quoted for whatever reason the price will NOT go up, but at the sametime if i finnish the job in 2 days the price does NOT come down.
Works for me mate and seems to give a good impression to the customer.
If your really stuck with what to say, just belt him around the head with your trowel........ stuff his mouth with sparky tape and then grate his teeth with your
tile file....get his old boy out and Silicon his japs eye! then explain that you would do it a lot faster if he stopped asking you fekin questions.
