Yeah, as others have said, the functionality of running a GT cafe and making money with GTW retail function never was a thing, so it's not glitched. I can see where you would think it would be a thing, tho, since there are a lot of similar functions in the game. I'm guessing that when Get Together came out, the devs weren't thinking about backward compatibility as much as they have since.
If you do run a bakery, tho, you don't have to worry about the food spoiling that quick when you place it in a display case. Most baked goods last a couple weeks or over in there.
I run a gallery and bakery together, but I usually don't use the retail interactions to sell the baked goods. I only interact with the Sims who seem to be looking at the artwork. Enough Sims buy the food since it's way cheaper anyway and they tend to gravitate toward that. I have coffee made in a pot, in case they want to help themselves to that, but it's free, haha. I can make enough money from the artwork to make it worth my while. The family that owns it is a large one, and the young adult daughter painter and baker grandma run the business. The parents both have jobs, so the daughter is getting on her feet with the retail business. I will move her out, and she will buy it from the folks. Every time she makes enough in the business to buy a 15,000 violin, I put it in her inventory. She will have enough soon. :smiley:
You could technically put a barista bar in a bakery, and then hire a barista. But you won't make any money from the drinks or baked goods sold from it. The barista baked goods would then be competing against the homemade ones, I guess, too.
