@JustBotBecky Putting spoken words into text erases the vocal nuances, emotional tone, and non-verbal cues that give human speech its full meaning. "No means no" is one of those things that makes sense on paper but not always, and doesn't make sense in reality but sometimes does.
@japan_nobunaga At some point, I predict shoppers will hand an employee their shopping list thru a hole in bulletproof glass. The whole shop will be just a stock room, no public access. The employee would assemble the item list and only hand it over after payment is accepted.
