If you enter a store and its elevator operator immediately proceeds to take you to an abandoned floor, that's probably a red flag. If upon exiting you happen to discover that the floor's contents are literally the one (weird) item you're looking for, that's kind of awesome—and also probably a red flag.

But if you wrap up your purchase with a creepy sales lady and exit only to be informed that the floor you visited doesn't actually exist, you might be on drugs. Unless you're Marsha White (Anne Francis), the naive leading lady in "The After Hours" who just wants to find a gold thimble for her mama. Before this episode, we'd never have thought shopping could be so scary, but what do we know? Clearly we haven't spent a night locked in a store with a bunch of living mannequins.
