So I have the basic idea for the SCP down. Basically, it's a phenomenon that occurs at a fast food restaurant(I'm leaning toward a Dunkin donuts for some reason haha) that causes people specifically working the closing shift to interact with "themselves" still working if they approach the drive-thru speaker after the restaurant is closed. The store still appears closed on all accounts except for the drive-thru window and speaker. For example, the lights are all off and the store is empty when viewing from regular windows, but the restaurant is still in full operation when parked next to the drive-thru window. I'm really not sure if I should go toward a more malicious reasoning behind this effect (kind of like a soul trap haha) or approach a weirder dimensional aspect to it (subtle/to large "reality" differences that are influenced by a nearby landmark or something else… I'm not really sure at this point) Depending on the route this concept could go, the duplicates would either not recognize the crew member and act "in character" or the duplicate would immediately recognize them and act with distress.
In any case, any feedback would be really appreciated! I'm kind of apprehensive since this is my first attempt at trying to write anything for the wiki.
