I started avoiding libraries because the librarians will not leave my Sims alone. For some reason, they have to sit right next to my Sim and start chatting even when I cancel the action. Now I take my Sims to the library after 9:00 PM when there's no one there. On the other hand, it's nice that the Librarians are Young Adults instead of another adult.
I think that gym trainers are worse than librarians. There can be 15 Sims at the gym, but the trainer always targets my Sim to train which instantly starts a friendship bar which often results in the trainer becoming a good friend of my Sim even though they haven't actually met. Instead of trying to avoid trainers, I started taking my Sims to a gym late at night when there are no trainers. Unfortunately, no matter how late it is, there are always one or two premade Sims who think that the purpose of going to a gym is to chat and not to work out.
Bartenders have gotten worse with socializing too. Lately, it seems that you can't order a drink without having the bartender start chatting with your Sim or becoming part of any conversation that your Sim is trying to have with someone. In the past two weeks, I've seen numerous bartenders stop tending bar so they can sit down and chat with customers. This happens a lot at the venues that have karaoke machines.
I've also seen a new issue with some stall vendors in Casters Alley. Instead of all three vendors opening their assigned stalls, one is always standing near the fountain chatting with other Sims. I have one vendor that consistently goes to Magic HQ where he spends his time chatting with everyone. Meanwhile. his potion stall is closed.
I don't want my Sims to be anti-social but I do want them to be able to get things done quickly so they can socialize after they're done. I think that when I cancel some townie's urgent need to chat with my Sim then it should be canceled and not delayed. More often than not these townies have just entered the lot and are nowhere near my Sim which causes my Sim to stop what I have them doing while they wait for the townie. It's always an adult townie that my Sim has never met.
