You just arrived at your night shift for tonight, telling your colleague that they can leave now as you will be taking over now...he sighs and goes out of the store and leaves in his car as right after that, you clock in. Several customers come and go but after some time, a guy enters and just takes an apple from the fruits area and places it on your desk, saying that that's all he wants so you cash him out. But before going he says this

The guy: you know...I always feel oddly uneasy when I come here at night for some reason...
