loading up for take home at all-you-can eat is dishonest and will get you banned from most buffets, if they figure out what you are doing
This incident makes me wary of this woman’s acumen
Many buffets allow take outs, if you do not want to eat in. They give you the take out container, and the size of the container determines the amount of food that is taken. I would not call that dishonest.
What they don’t do, is let you eat first and then take home left overs or seconds. If you put extra on your plate, and sneaked it into containers, that would be objectionable to them, and dishonest. Of course, if your eyes are too big for your stomach, all that food you can not eat gets dumped.
It has the same economic impact on the business.
Any way, I usually avoid all you can eat buffets, and order from the menu, so if I get full before I am finished I can take leftovers home to the dog.
