"Sorry we have no tray," Hal smiled. "But at least the glasses are right. You cant drink champagne cocktails from a water glass."
I may be unwilling to use him as my goto guy for examples of how to do proper punctuation, but I WAS prompted to go to one of my own "finished" books, The Saga of Travels Far Woman, Book I, Summercircles, and search for "glass" checking each occurrance until I located the one (of 33) where I located, "She sits alone with her $5.00 frost-textured pitcher of ice water and a matching tall, thin, textured glass instead of a regular water glass, but is no longer gulping the contents as she did, much to the well-hidden amazement of the clientele."
I then added the part in red. In one version, I had described it as an 8 oz. glass, but then I rethought and decided I was NOT sure that the tall, but thinner glass might not also contain 8 ounces of liquid. It might have been less cumbersome had Jones just had his characters tell me the proper name for that tall, thin glass. I already knew the name and shape of a champagne glass, even though I'm a total teatotaler. (I DID trust his spelling enough to allow him to teach me how to correctly spell champagne. And, yes, I do realize the kudos may really be owed to his editor.)
Guess I can't really call it "finished" if I'm willing to contemplate that type of addition, even if I might eventually decide it interrupts the flow too much and remove it.
