I walk past sukkah stores or even past eichlers and see a small sukkah they advertise outside. I'm assuming that's a 4x4 from the look of it?
Would a 4x4 fit a small square folding table?
It fits a card table for 2 ppl. If nobody gets up and nobody leans into the table/nothing in the middle/everyone has mini plates, maybe you can stuff in 3 ppl for one course.
