As for the coffee center ... here's how I handle it:
First, you throw a collar and leash on the customer, and don't let him go until you and him have together gone over the exact location of all equipment. I take some masking tape with me, and put notes right on the walls and counters in the exact spots where things will be.
Next, be sure to ask the customer what other (similar) businesses he has ... or that he is trying to copy. Then, go look at their gear.
Finally, if there is ANY doubt, get ahold of the vendors, and get the info direct from them.Even if the stuff has plugs - check the nameplates. Far too often, I've had equipment come with the wrong plug.
ALWAYS plan on the coffee center needing more circuits, more power than you plan for. Here's to going up a pipe size, pulling extra circuits, etc.
In my current project, the "drawing" indicated TWO 'normal height' receptacles. After talking with the customer in painful detail, that same wall ended up with ELEVEN receptacles, on eight circuits, with one near the ceiling (soda ice maker), one under the counter (soda pump), and six above the counter.
