Ralph was a little off-put by the potato chip eating lady's demeanor, but he didn't let it show. Instead, he smiled, nodded and grab the things she wanted and put them in a bag. After that, he grabbed the 300 G coin and said "you're welcome to make change yourself in the register next time I'm not around. It isn't locked," the store owner pointed out, opening it to make change. As he finished doing that, Ralph handed Whiskey her change, saying "and here's your change. Thank you for stopping by! I hope you have a great day." He really did mean that, even if she didn't really seem to be in the mood for small talk.
