I know a guy who's family net worth is $2+ billion. When he goes to the movies, he brings pre-popped popcorn in ziploc bags and shares with his friends.
Others might say that's the way to keep friends, when you have 2bn.
NO OUTSIDE FOOD OR DRINK.
lots of rich kids i knew in college dealt drugs. think about that one for a minute. same exact (rule-flouting) behavior as poor folk - but is it because they were poor? or frugal? was it because they didn't want to spend their own money on their own drugs, or because they enjoyed flouting the rules to get free weed/coke/x/whatever?
