Once upon a time, when I was a college student, a friend got engaged and registered at Big Department Store (that worked on commission). Several of us pooled our money to buy a gift from the registry, but when we went to the store, looking like college students, the sales clerks completely ignored us. I mean, they looked at us, sneered, and looked away. That made me so angry that I waved our money around and started shouting, "Hey, we have money! Is it not good enough for you? We'll be happy to spend it somewhere else! Where's the manager?" and so on, in that vein. Of course my friends were ready to crawl under the nearest rock, but damn if we didn't get waited on. But as retribution, I told the clerk we weren't going to buy the expensive thing we'd wanted to (and could afford), because we didn't want to give their rude asses that much in commission. The manager was pissed, too. Sadly, I couldn't convince my friend to change the registry to another store.
All that to say, your peeve is other people.
