For me it is when companies/services market themselves as donating to XYZ cause if I buy their product. If they want to donate, they should have already done that with the money they have. Asking me to give them profit so that they can donate is so obviously pretentious.
I fucking cannot stand when salespeople use basic human decency as an opening for a conversation. We made eye contact, I nodded and acknowledged your existence, I do not want to talk to you about how quickly you can remodel my bathroom. I can see your display, if I was interested, I would have asked you about it. Yes, I’m going to be rude to you because you abused my being polite to you. Fuck all the way off.
