I have worked in the pizza industry for years and have noticed that people order the same type of pizza in spurts. One night all we sold was pepperoni and bacon. In fact the first order of the next morning was also a pepperoni and bacon from some one who had been thinking about it all night. Also if one person orders on kind of drink, will serve that drink alllll day. I know it's just pizza, but it speaks to the fact that we are all connected even if you think your not.
