I finally had enough. I actually wrote this to a client, returned her deposit and told her to take a flying leap.
Client: I contacted you on the 3rd and told you I needed these files to the printer by the 20th and you assured me there was no problem. Now I can't make the deadline and would like to know why you didn't do what you said would be able to do. You're inability to meet the deadline really put my project behind.
Me: Gee. Do you think the fact that you went on vacation between the 5th and the 20th and did not look at any proofs or contact me once during that time might have had something to do with it? Or the fact you didn't tell me who your printer was? Or wait, maybe the fact that you gave me the wrong text to use and then needed it reset? Maybe? Ya think?
