The pretty 16 year old NAME_1 is helping out in her mom's chlothing store. An older gentleman is browsing women's clothing with a girl about NAME_1's age. NAME_1 overhears the girl saying: "It looks pretty, grampa but I don't feel comfortable wearing it for you". The man approaches NAME_1, saying: "Hello, Miss, I'm looking for a present for my granddaughter NAME_2 but she's uncomfortable presenting the risque clothes in front of me. Could you try on some clothes for me and NAME_2 that I've picked for her? I'll pay you $20". "Sure thing, Mister", she replies brightly after a short hesitation. "Don't mind me", he says, reaching for his phone to take pictures of NAME_1. There are snide remarks from NAME_2 when NAME_1 is showing too much.
