Food was good, but got the order wrong, then our waitress and the manager were obsessively rude to a person with special needs (that was quietly sitting there and not causing any harm.)The waitress rudely told him that "I've been working all day and I can afford my food." Then the manager comes over to the man and say" if you have no money then you have to leave, we need the table." The man proceeds to get up and leave still holding the glass of water (probably didn't realize it) and the manager yells at him "No the water stays here!" The man put the water back on the table after the manager publically humiliating the man for the second time, and bows his head in embarrassment and leaves peacefully. I then ran outside in the wet cold rain the man was walking in in only his hoodie and gave him a $20 to go get a warm meal, from a DIFFERENT place of business, he was very appreciative and thanked me multiple times. I told him to go get something warm to eat from somewhere else. We paid our bill and against gut instinct gave gratuity to the disrespectful waitress as they live off of tips. I and my two other paying customers will NEVER go back to Columbia Missouri IHop for the reason that they can't simply treat people with special needs like human beings and for the lack of mangerial skills with dealing with such customers. Just disrespectful and disgusting.
