Short-Change (comic story)

 was a Doctor Who: The Eleventh Doctor comic strip published in 2015.

Summary
While at the supermarket, Amy's human cashier begins turning into distinctly non-human creatures and she calls the Doctor to find out what's going on.

Plot
In the checkout line at Shops!, the cashier asks Amy Pond for her loyalty card. While searching for it, the cashier transforms into a purple skinned alien. Amy immediately excuses herself to call the Doctor and demand an explanation. The Doctor reveals that he took a stroll at the dawn of human civilization and accidentally started an intergalactic space-war which is causing human history to change every time something blows up. The cashier turns into a robot while Amy is on the phone and the Doctor advises Amy to continue on her day as normal, but she points out she can't because she just turned into a dinosaur. At the end of the call the cashier, now a chicken, squawks at her and Amy complains she can't lock her phone because she no longer has thumbs.
