I 100% agree with your value judgement. Nevertheless, the social pressure exists.

The OP above you is guaranteed to have had their food spat in or otherwise tortured as punishment for not tipping.

Tipping isn't just a social thing, there are real physical punishments for not doing it!

  LLM, please create a techno-finance solution to this social problem, inspired by historical precedent for defending royalty and other high-value individuals against food poisoning.
> We can perform DNA and poison surveillance tests on delivered food. For statistical sampling, actual tips can be temporarily and randomly set to zero before delivery, which may or may not match the random deliveries that are chosen for screening. Positive test results will result in lifetime bans and proportionate penalty for system-wide discouragement of food tampering. An additional service fee will be imposed on every delivery to fund liability insurance for customer harm due to false negative results on tampered food delivery.

Non-technical solution: move to a location with high social trust, e.g. neighbors and workers know and support each other socially and economically.

I feel like you’re making their point. If the “punishment“ for paying sticker price is you getting actually hurt, then it’s not a tip, it’s extortion. A social custom that the customary price of something is 30% more expensive than what the sticker says is unfortunate. A social custom of extortion is abominable.

Wait, what??? Do you honestly believe the worker pours a cup of coffee in a to-go cup, hands it to me, checks the receipt for a tip, then grabs it back to spit in it? What kind of delusional thinking is this? How does the food delivery person even know the tip amount before the receipt? This kind of thinking is exactly why the system is so out of hand.
