So many people missing the point. I'm not annoyed at people taking my herbs at all. That's what they're there for. I just found it hilarious that they took 4 herbs, but left the last one so that you'd think that the herb batch is fresh. Somebody was being a troll, and I find their trolling funny.
If I didn't want people taking my herbs, then I would just lock my homestead. I'm not enough of an idiot that I don't realise that.
Don't worry, i got the point. I used to do that to people, by using a combination of rain casting, Pick excess herbs, wait for rain casting to go away, then if someone tried to pick one, it would say there was none left even though there should be.
