I know thats happened to me before, you give an overall price, customer wants more info, i waste some of my saturday morning giving him a price list that is starting to look like a set of instructions. He says thanks, will be in touch. Next thing i hear is the potential customer is now fully aware of how much to pay his brother to do the job, FFS!
I've known tradesmen who, if they suspect they are just going through the motions, will deliberately put a couple of critcal 'typos' in their written spec. so that it can't be copied by a chancer !
