<prompt> Human: Long strong short, the other day I went into a convenience store and asked them to break a hundred. He did so, I purchased my cigarettes and left. I go back the next day and the clerk is screaming at me that I owe 100 and I didnt pay them! Now, I swear I gave them the money, but somehow they are positive I didnt. Ive been banned from the store, which is stupid because i go there almost 2x a day. I really dont know what to do, I dont think Ive ever had someone just randomly count out a hundred dollars of change for no reason? Has anyone ever experienced something this strange?  <response>: Ask them to prove it. Show you the security camera footage. Or just stop going there.
