I think it's nice for the first times one asks Clint for cracking.
But in the late game I would like to give 100's of geodes to Clint, pay and get the content completely next day at Clints (or maybe per mail).
Oh I like this idea a whole lot! This is
exactly the type of late game buff that should happen once the Farmer reaches some type of goal. Maybe:
Cracking 100 Geodes - "Hi Farmer, you really seem like a dependable source of g-- uh, I mean geee...ooodes. Yeah! So if you want to, just leave your pile of useless rock clusters with me and I'll crack them after 4pm today and give you the proceeds tomorrow morning. Well, as long as it isn't Friday when I check out the boilers and then Emily."
-- failing the above check, you get the following --
Making 1,000,000 g - "Hi Farmer, it seems you turned all those years of playing Tycoon games online into something IRL useful and can now afford our concierge service. Leave those filthy potato stones with me and I'll crack 'em open after hours and you can pick up what I found tomorrow morning, if there's no Festival happening of course!" Clint ponders his Calendar. "Sooooo many Festivals..."
-- failing the above 2 checks, you get the following --
Reaching Year 3 - "Hi Farmer, I keep seeing you around but not often enough. I thought I'd set up shop far enough away from the town center but you got me beat, are you still part of the community? Anyway, as a value-add for the elders of the community, you can leave those geodes you've been hoarding with me and I'll return totally all of what I've found the next day. However I have a deal with Gunther that anything new goes to him first as you seem not to care much about finding minerals and whatnot."
For #3 there is a rare chance that Clint accidentally misplaces a second Prizzy Shard or Diamond and you get Aquamarine or Soapstone or something. But of course you'll never know unless you cheat and use a Seed Predictor. You ignored Clint too often for 2+ years, there are consequences.
