Quicksave

Kills NPC in the most brutal way possible

Loots

"Huh, so that is what they have"

Quickload

Many such cases

I wish the logic was more like a real store (some roguelikes do this so it's not even a new concept) so you can grab whatever you want and it's only stealing if you try to exit the store without paying.

It's more like:

Quicksave

Pickpocket an NPC - 70% chance

THIEF! GUAAARRRDDSSS-

Quickload

Repeat until you succeed for every single NPC
