I have a group of six young adult sims living in one house. Only two of them have the mixology skill. The mixologists are the only ones that autonomously make drinks. The other 4 sims never touch the bar. I used to keep the bar in the household inventory unless they were having a party. I have it out now, because I'm trying to get Amanda to complete the Culinary aspiration. She has to make drinks for her job. I wish I could stop her husband James (the other mixologist) from using it. He seems to like to use it more than Amanda does. He drives me crazy. If I don't have him busy doing something else he always heads for the bar, so I understand your frustration. I'm constantly yelling at James. LOL
