That's pretty neat that nintendo thought of that, but can it perfectly safety proof? Think about it: in RSE, you have to pay to get into the Museum at Slateport, where you'll save someone from team aqua/magma. What if you didn't have any money, no items, and no Poke Balls? What then? You couldn't move on...

i see what youre saying. spend all your money on items and then throw them all away. i wonder if theres something to prevent you from tossing your last item. does someone wanna try it?

maybe you could wait until someone wants to battle you again. even still, as long as you had a zigzagoon, you could use pickup to get an item for free and then sell it. but if you didnt have any zigzagoons you could theoretically trade with someone for a pokemon which was holding an item. so the real problem would be: you have no money, no items, and only one pokemon (which doesnt have the pickup ability) so you couldnt even trade. my guess is you would have to start the game again.

this is great - trying to figure out ways to get stuck...

You don't have to reset your game or anything else, the attendant just asumes that you are a lagging member of the group and lets you in for free, and she will continue doing that until all but the one who gives you TM 46 has left.
