Something similar happened in Albuquerque recently with a doctor/medical executive. She has a salary of almost $300k a year. It’s unclear what makes people do this - entitlement? Greed? For thrills? I can say though from experience running a small independent retail art supply store, the people who stole from us the most were well-off women who were otherwise good customers. It seemed like they thought they were entitled to a “special discount”, like they resented that we consistently made money from them and didn’t offer special deals.
