Totally get it, had a client bring donuts and then lecture me on font kerning for half an hour. That free snack suddenly comes with a side of micromanagement. It just makes the whole vibe feel cheap and transactional.
Watched this happen at my kid's school bake sale last week. A parent brings fancy cupcakes, then spends twenty minutes telling the teacher how to run the reading corner. See it all the time, my neighbor gives you tomatoes from her garden and then feels she gets a say in how you trim your hedges. That little gift just makes them feel like they bought the right to nitpick your choices. Honestly it turns a nice thing into a transaction every single time.
Used to find it charming until a guy handed me a latte and then spent ten minutes questioning my pipe thread choices. Now I see free coffee as just the opening bid on unsolicited advice.
