Here's a customer-relations question for you... I just finished building the biggest frame I've ever built (72x44). I now realize that I should have added a hefty PITA tax to the job. I priced it out at materials+markup, not realizing that it would take the better part of a day and some rearranging of the furniture to actually get this thing built. Okay, lesson learned for next time. So the question is this: do you tell the customer anything? Like, "I should have charged you more. You're getting a real bargain here!". Basically I want to set future expectations. I don't want her to bring more oversized work expecting the same price, and I don't want her telling her friends how little she paid for the job... Or do I say nothing, chalk it up to experience, and quietly readjust my labor charges for super-oversized work accordingly?
