``Today my favorite kind of atmosphere is the airport atmosphere. [...] my favorite kind of food service, my favorite kind of bathrooms, my favorite peppermint Life Savers, my favorite kinds of entertainment [...] my favorite conveyor belts, my favorite graphics and colors, the best security checks, the best views, the best perfume shops, the best employees, the best optimism.''\cite{warhol:1976}
