You've picked an apt title: "Luncheon is served"! 👍
I'm glad you wrote about extension tubes. I forgot that one could use it to make a regular lens into a "macro lens" with decent results. Back in the day, when I used to shoot weddings, I tried using extension tubes to get a closeup of wedding rings. I had mixed results because the depth of field was very narrow, and it took a lot of patience to nail focus.
F.16 aperture looks like it helped to keep important things sharp!
Did you do any edits or post-cropping?
