My judgy pants are giving me a huge wedge after witnessing this ...

A sign in Waitrose (yes Waitrose, not '5 items or less' Tesco) saying "Magazines and Stationary".

I'm still twitching.

goes for a lie down and a stiff drink

Are you sure it didn't say, "Magazines ARE stationary" ?
Please tell me it did.

Were the magazines moving around?

Sure it wasn't Tesco?

Did you use a zeugma in your OP?!
