> There, meaning working absurd extra hours in order to deliver to the client as reneging would mean I have to own up to the client the fact that I totally fucked up the scoping (usually it's scope creep or changing requirements, but you can't really blame them even if it's their fault). The client for which I did the four 20 hour days had a project manager that committed to a milestone delivery with their client and did not run it past the dev team. So I did everything possible in order to deliver for the client. Were it that I underestimated the scope of work (which I have done many times), I definitely would have conveyed that.
