Client: You should have indicated a problem with the app sooner.

Me: It was only just made available to me to launch. As soon as I saw the problem, I flagged it.

Client: But you should have looked for a problem sooner.

Me: I just saw it for the first time. I wasn’t involved with the project until now. You just hired me. 

Client: That’s not true - I sent you an e-mail three months ago about it. Where I said I found someone to make the app at a lower price. Remember?

Me: I think so. How’d that work out?
