I’d been asking for a high-res copy of a client’s logo for weeks, and they kept giving me a black and white, 47 kb version of it.
Me: I’m sorry to keep bugging you, but this copy really isn’t good enough. Your website HAS a better version than this on it – can you send me the best quality copy you have?
Client: That IS the best quality I have.
After some prying, it turns out the client didn’t pay their designer’s last invoice so they refused to hand over the files. One had been uploaded to the website, but the client hadn’t made a copy before stiffing the last guy.
Long story short, I got paid in advance, extracted the PNG from the site while feeling weird doing it, and found a reason to say goodby to this client ASAP.
