Why Pay For Code, Then?!

I get a phone call from a client I built a website for.

Client: “The site isn’t working right.”

Me: “That’s strange.”

I download a page and take a look at the code.

Me: “It looks like a bunch of the code is missing. Did you have anyone modify the site?”

Client: “No, nothing like that.”

Me: “Well, there are entire chunks of code missing that were there yesterday.”

Client: “Oh, yeah, that was me. Some of the code seemed unnecessary. Back to the issue at hand: why isn’t the site working?”
