I've been on both sides. I've been the client, where my T has forgotten my previous session. I had to run through a few points to refresh her memory. I've also been the therapist who just couldn't for the life of me remember what happened the previous week. Usually it takes 1-2 sentences for them to jog my memory. It sucks. But, we are human.

In regard to the coffee - I'm glad he mentioned that he needed it. At least then he will be able to focus completely on you. I've been in session as the clinician where I'm just dying of thirst and I'm thinking "OMG I sooo want my Pepsi right now". It ended up being harder for me to focus if I didn't just get it and quench my thirst.

I wonder if you can reframe your thinking about the event. Instead of viewing it as the coffee is more important then you, think of it as: you were important enough to him that he wanted to ensure he was focused on you by meeting his needs first. This, after all, is what the therapist is teaching us to do. You have to meet your own needs before being much help to others.

I think the comment about what's on the mind of a therapist, would have shook me a little bit as a client. But if your T is as awesome as it sounds like he is in previous posts, he seems to be in tune with you, and with you in the moment. Hold on to those feelings.
