My first game is so embarrasingly bad and full of free models, I think it has a virus or something. I made it in 2015 on an old account. https://www.roblox.com/games/335349278/THE-PLACE-OF-RANDOM-STUFF

You could do so much with this concept. Build on the NPC dialogue and give them more things to rant about. The player should also have to serve the customers at the till and should have a phone to call the manager when things get really chaotic.
