Oh my goodness that's terrible - how effing rude!! That's just... not okay. I'm currently keeping one of my towns on hold at 642 bells for turnips and whilst I'm not worried so much about stealing (yeah there are things to take but not much and the turnips sell for a million bells per load.. they'd be pretty silly to waste time on flowers at that point..). But I'm struggling with the communication, as I don't mind offering and helping out of course, but some manners - and some patience - would go a long way. Live qnd learn I guess, and some people here have an awful lot of living and learning to do imo is all! I'm going to add a check word from now on (include the word "___" in your post/VM/PM to me or it will be ignored, thanks! That should lower my stress levels a bit, as I can comfortably ignore anyone who can't clear that minimum bar for communication.
I'm up now (obv!), though 2+ hours later than I'd aimed. So can come when it suits you.
