@drew9498 , while we don't have a supermarket where your Sims can enter, we do have the opportunity to own other retail shops if you have the Get to Work EP!
By "Movie Theatre Attendant" , do you mean the person who takes your tickets and directs you to which theater your movie is showing in? That is usually the job of an Usher, and is not an adult "career" because it is something more suitable for teens as a part-time job (at least in the U.S. -- it might be different in other countries!) I used to work in a movie theater, and the only careers were in management! But your suggestion would be good for a teen after school job! 😎
For Car/Motorbike Mechanic, maybe if they add cars or motorcycles to the game, they might include this career!
I've seen several requests for a Maid career, and a Nanny/Child Care Worker career!
We don't have an Archeologist career exactly, but if you have the Jungle Adventure GP then you can basically live like one! To tell you the truth it is probably better this way because you get to send your Sims on adventures and brush up on your Archeology skill (pun intended!) and find rare finds! This can be a lot of fun and your Sims can live off doing this! 🙌
