“You can serve high tea around the dining room table, but afternoon tea is more of a living room occasion, with everything brought in on a tray or a cart.”
“The hour [...] can be anywhere between three and six o'clock in the afternoon. The general rule is that the earlier tea is served, the lighter the refreshments. At three, tea is usually a snack -- dainty finger sandwiches, petits fours, fresh strawberrries; at six, it can be a meal -- or "high" tea -- with sausage rolls, salads, and trifle.”
