1) Has this ever actually happened to you? If not, like most fear of success, it's probably manageable to put it off until it actually happens. 2) Clients are buying your availability, they aren't buying bump-what-you're-doing-now. (That's a separate service, and ridiculously expensive.) If they find makework for you on the 29th, you tell them "Gotcha, I'll tell you when it is done and we'll count it against this month's allocation." If they balk at that, you can tell them that happily your email address works all 30 days of the month and that they can get in their requests quicker for faster turn-around. Of course, the ultimate protection against clients being impossible to work with is not working with them, but -- again -- I'd wait until you actually had a problem before rejecting them for that.
