Some of the stores have different closing times often a few hours difference, this is a problem if you want to just get something really quick near closing (like food), as If you run into the shop as the owner decides to close he will shut AND LOCK THE DOOR with you inside and tell you to leave... If you try to pick the door the idiot shop owner is standing there and gets mad that you are trying to leave... If you do nothing he will attack you because you cannot leave. He normally sticks RIGHT NEXT TO THE DOOR until you leave but you cannot BECAUSE he will stop you from lockpicking his door to escape.
This happens so much to me it is rediculous
Also You can easily get stuck inside shop doors- IN the actual door. If you scoot your character too close to a closed door he can get absorbed inside of it, and if the shop keeper is standing on the other side he will consider you to be inside the shop and start telling you to leave but you cannot without a outside member lockpicking without being noticed.
This mostly happens when you are trying to steal from stores at night if you get too close to the door u can become trapped.
