Grout lines look like they've been washed off way too much. Tiles are stepping quite a bit.
Not the best tiling that.
I thought you were DIY when you first asked but you say this is a customers job. :-/
You need a tool like a Fein Multimaster with a grout removal head on it. (Available from www.TradeTiler.com) or a grout rake (also from TT). But it'll take you ages with a rake. Then re-grout.
