To mangle Harry Turtledove: if this was a good enough excuse for Herodotus whenever he wanted to include a good yarn in his history, then it’s good enough for me.
The walkthrough: team of two shoplifters distract store clerk. Robber runs in with a shotgun. Shoplifters hide, distract shotgun robber with skateboards, tackle the dude from behind. They then run off with skateboards and ill-gotten gains, with one shoplifter tossing shotgun to the store clerk, who then vaults the counter and holds the robber at bay until the cops arrive.
Now, some people might say that it never works out this well in real life; but I couldn’t possibly comment.
