Night Shift Customer

You work the night shift as a cashier in a small minimarket attached to a gas station somewhere in the backcountry.At night there's only the highway, a buzzing neon sign and the occasional pair of headlights cutting though the dark. Your job is simple: mop the floors, take out the trash, restock shelves and serve anyone who decides to pull off the road.But the longer you sit behind the register, the more you feel: something is wrong with these quiet nights.

One of your regular customer is no longer human.And whatever took their place doesn't know everything they once told you. 

AI-driven customers and live conversations

Every customers in NIght Shift Customer is a separate character powered by a large language model:

• Real dialogue, not canned lines.Customers chat with you about work, life, crashes on the highway, local rumors, strange dreams and missing people. They can joke, be rude, ask questions or give unsettling answers that aren't scripted/
• They react to how you talk to them.Be polite and respectful and people start trust you, share details and personal stories. Interrupt them, mock them or act like a jerk and you'll get cold, annoyed or outright hostile reactions - from passive-aggressive remarks to open threats.

Memory and relationship.The AI remembers how you spoke to it on previous nights. Some people see you as "decent guy behind the counter", others as "a loud-mouthed kid at the register".Relationship level affects how honest and detailed the are, how much they're willing to open up, and whether they'll talk about what's really happening out there.

Routine shifts turning into horror

When the store is empty, you work doesn't stop:

• Cleaning and maintenance.Sweep the floor, wipe up spilled drinks, take out the trash, check fridges, turn lights on and off in different zones.
• Stocking shelves.Bring boxes out of the back room, place drinks, snacks and other goods on shelves, keep an eye on empty spots.
• Working the register.Scan items, calculate totals, take cash, give change. Sometimes it's straightforward - other times someone "forgets" a few dollars or argues about the price.
• Cheating - from both sides.AI-controlled customers can try to underplay, take too much change or "not notice" you mistake. But you can also "accidentally" make an mistake in you favor... if you're not afraid they'll remember.

Over time, small oddities stack up: a glance lingering on the CCTV a bit too long, identical stories from different people, a feeling that some customers repeat the same line with slightly off intonation.

Who among them has been replaced?

The core horror of Night Shift Customer isn't loud jump scare - it's doubt and paranoia.

• The monster copies person, but their conversations with you.The creature that take someone's place knows the victim's appearance, background, habits and general facts - but it does not remember the personal conversations they had with you and doesn't genuinely feel how they really saw you.
• Listen, remember, connect the dots.One client talks about strange crash, another about a patient with no memory, another about an old cult where the gass stations now stand. Put these stories together in you head, notice who said what and how they react to you questions.
• Test the suspicious ones.Ask about what you discussed last night. Bring up inside jokes. Ask about small details: favorite drink, pet's name, a past incident they once mentioned. A real person will remember - or at least react in a believable way. The impostor will get confused, dodge the question, become nervous or, on the contrary, overreact aggressively.
• Make decisions under pressure.In critical moments you'll have to decide who to trust, who to let into the store and who to keep at a distance. A bad call might mean you're not around for the next shift.
