<stop me if I've already told this one> A long time ago I worked in a production photolab. Work would come in during the afternoon, I'd do it the next morning, usually before lunch. But my boss had a system where each type of work had a day count, and nothing left before that daycount was up. So I'd put the work in a bin, and every day I'd check that bin to see what was due to go out.
At first I thought this was very poor business, and told him so (I was the same, even back then). He explained to me that, if you gave it to them the second it was finished, they wouldn't be appreciative, and would come to expect that kind of service on all their work. Some would even be suspicious of something that didn't take days to do.
Anyway, the windup is that I came to agree with him, and used a similar system when I had my own commercial lab.
And today? Today I tell them "I'll have it for you in a week or two", then give it to them in a week. Ok, maybe 5 days
