At 3am, after finishing a website template for a client who had to have it “by 6am their time,” I sent an email letting her know that it was finished. The next day I get a call:

Client: I don’t appreciate you staying out all night when you should be working on my project.

Me: I’m sorry? I was working all last night. As you can see, I sent you an e-mail - 

Client: I see that. At 3am. Do you think it’s okay to party all night and then work without sleep at 3am? It’s very unprofessional and morally reprehensible. 

Me: What makes you think I was out partying?

Client: Why else would you be up at 3am?

Me: You gave my 24 hours to do 18 hours of work. I had to stay up 

Client: Don’t try to use math on me!
