Excellent list.  I happen to put a decent amount of half and half in my coffee (maybe 1 T : 10 oz of coffee, yeah I have a problem with caffeine and milkfat for breakfast). If I accidentally put too much or someone else adds my half and half I call it a milkshake to remind myself that it is a milkshake. I try to stick to places with brown uniforms or wooden counters so I can say "this color is perfect!" Or "just a bit darker than your hat" to get close set to what I'd like. I've noticed it really helps, even if the server is overweight or worse.  Pro tip: ALWAYS do this at those drive through coffee/espresso stands and bikini coffee stands. They make it look like you're drinking coffee flavored milk otherwise.
