Walking around the stores you find one where the only employee just went to the backroom for a sec and there's only one lady inside. You simply just go inside, fire the dart into the back of her neck, and quickly say to the gun "mental: ignore the dart and me completely". Then the lady just rubbed at the back of her neck around where the dart was. Not really paying attention to the dart, but rubbing at the sore patch of skin the dart was embedded in. Smirking you thought about what type of changes you'd like to put in when the employee came out from the back with a few items to restock and she saw you had a weird sci-fi gun-type thing in your hands... and a woman with a metal dart about an inch long sticking out of the back of her neck.
"Wha!? Miss do you need help!?!" the employee asked extremely concerned.
the lady you shot was confused by her tone and said "I was just about to checkout so-"
"But you have a dart in your neck! I think HE shot you!" the employee said pointing at you
"Who?" the lady asked as she looked directly at you and she rubbed the back of her neck "I don't feel a dart..." Trying to quickly think you go behind the woman and yank out the metal dart an- "Ow! wait... You did shoot me, that was a dart, and how am I not bleeding?!?" the lady asked as the mental changes immediately ended. Now they were both facing you, and you remembered you had to aim at the back of someone's neck...
