Heathrow, like all airports of the world does not have enough seats for people to sit down. It needs about three times as many seats as it currently has. And, although better than most major airports, if still does not have enough COMFORTABLE eating and drinking places - the cafeteria-style restaurants and fast food outlets do not constitute bars and restaurants with the required ambiance, that would make me want to eat and drink there. The so-called "duty-free" shopping, takes up too much space - airports could make just as much money from them by cramming their shops into smaller less ambient spaces, and making more room (and money) for bars, restaurants and seating.
