I think you're missing my point. Yes, it seems more wrong to take money than to take a drink from the fridge. The researcher in this study is saying "aha! taking a drink is exactly the same as taking money, therefore human beings are illogical thinkers in this scenario!" But it is in fact logical - it's based on the anticipated response of the person whose money/drink you're taking (and if you don't know how it belongs to - the general expectations of people in your society/community). Also, I'm sure that there are societies in which people never take drinks from other people, and consider it the same as taking money. A comprehensive study would have covered more than an American college campus.
