Once we met a billionaire who used to say "Food gets in the way". Yes, we waste too much time on food, we look for a restaurant, we wait for a table, we wait to order, we wait for the food, we wait for the check, we later wait to recover from the food coma and search for a Starbucks (more standing in line). In that sense the whole aspect of food takes so much time that it is far more expensive than you might have thought.
Think of how much could have been accomplished or created while you did not have that lunch.
