I don't know.
20 Ounce drinks pay the bills. I'd rather be making enough money to keep us in business, have nice equipment, and pay my baristas and myself a living wage.
Jay and all--
Do you think the fact that high quality coffee often changes dramatically as it cools provides any justification for large sizes? Or does the "Big Gulp to Go" symbolism simply de-value the product, trumping any opportunity for the appreciation of complexity?
I'm not sure myself. Twenty ounces in a vac pot with ceramic at a table is cool; 20 ounces in a paper cup while driving to work . . . not so much?
