So, I was wondering if there is a term for people that - as the title suggests - prefer to buy stuff/ support businesses, even if they are not that good, only because they know the owners (they are friends with them, they are relatives etc.). In other words, they feel compelled to support them just because they know them not because their products/services are satisfactory.
I'm trying to find a negative word that suggests that this practice is wrong.
Online, I came across the term "reciprocity" and the experiment that Phillip Kunz conducted but other than that is there a term ?
