I don't understand why restaurants do this: Be cheap.
We ordered wings today and in the take out package we found exactly one carrot and one celery stick. They shouldn't have put anything in if there was such a shortage. At least I would have said, "Oh, they forgot, that's OK". I would have paid them more if I it meant I could get more vegetables. Oh well. They saved a few cents, lost a customer and received a poor review on Yelp.
