I was raised with the idea of eating while sitting at a table. I even find that restaurants provide the same accommodations. I am not sure how you eat without using a table. Do you balance your plate on your stomach? What about a glasses, silverware and soup or salad plates? Or do you just stand up and eat with your hands instead of silverware?
Anyway I have never had any issues sitting at a table. When camping I end the day sitting at the dinette reading, working on my laptop or just resting.
