Going by the timestamps on my photos from March rotfl2: We were at the 8:30 show. Corn bread and salad was brought out immediately after we were seated. Ribs, chicken, mashed potatoes, beans, and corn came out around 9. Strawberry shortcake was delivered (with song) about 10. So it's probably not practical to eat and then leave.
No, that wouldn't work, lol! Oh well, I guess I will scratch that one off of the list of things to do. Thanks everyone the the valuable advice.
