They are supposed to be for a scene with the juice stands on the beach but I can't seem to find a way to get that scene to happen, so maybe it wasn't fully implemented yet.
no, the scene is implemented you have to go on the weekends saturday/sunday at noon with the paper cups and on the beach on the far left and press on the juice machine, this will triger the scene
odd, i have the cups in my backpack, and i tried at morning, noon, afternoon, and evening, on both sat and sun and it didnt work
the machine doesn't seem to light up with an outline like it is interactable. there is one instance where a girl is leaning into it, and she is not interactable either.
then i dont know what to say man, i did it and it gave me the extra scene but you have t0 have mia lvl3/4 too idk try to lvl up mia if it doesnt work then either then i dont know
if you fully max out Mia's levelling, go to the beach in the afternoon on a weekday and go to the area where you collect shells, after you do that click on the drink machine at the food stall, and it should activate. If that doesn't work go on a Tuesday afternoon.
