OK Coffee is a personal project, one where I'm the client. If I could get a quid every time I've submitted a design and someone else has gone ahead and presented it to the client without me there to justify the design decisions - I would be on a beach in Bali. When you climb up the ranks it's just one of those things that happens. I actually love presenting work to a client and actually explaining the design choices, rather than 'could we see it in green' and just going with that as feedback. No you can't, it would look shit. Here is a more relevant colour instead.
