Get a freshly poured McDonald's shake. Stick a straw in and suck. It's a very soothing feeling--almost primal. It's specifically designed that way. The straws used at McDonald's outlets in Japan are reflect the experience of breastfeeding. Rocket News 24 quotes Den Fujita, the founder of McDonald's Japan, in his book Den Fujita's Business Strategies 2: Overwhelming Business Strategies:
When humans drink something, the speed that produces the most delicious feeling is the speed at which babies nurse…McDonald’s straws are designed so that when used with a shake, the speed will be the same as that of an infant drinking breast milk.
Drinking a McDonald's shake is supposed to reflect an essential infantile experience of pleasure.
