(I have an identical twin sister. The only noticeable difference between us is that her hair goes past her shoulders while mine is chin-length. This happens when I am shopping at the grocery store she works at.)
Customer: Hey, *Sister*! You got a haircut. Looks good.
Me: Uh, thanks, but-
Customer: Are you guys still having that sale?
Me: Sir, I’m not *Sister*. And, I don’t work here anyway.
Customer: *laughs* Good one. But, seriously, *Sister* is the sale-
Me: Sir, I’m her sister, and I don’t work here.
(I try to push my cart past him, but he grabs my arm and glares at me.)
Customer: Okay, it was funny the first time, but now you’re just being rude.
(Luckily, my sister happens to be passing by at that moment and rushes over to us.)
Sister: What’s going on?
(The customer looks from me to her and gets a terrified look on his face.)
Customer: CLONES!
(He then ran away screaming, knocking over a display of tea boxes in the process. My sister and I stand there dumbfounded for a moment.)
Sister: You saw that too, right?
Me: Yep. *pause* Do you need some help with those boxes?
Sister: Nah. Just promise you’ll put this on Not Always Right when you get home.
