One thing that hasn't been mentionned in the thread is you could hire a employee with the badge you need. While browsing for employees yesterday, I saw one with a gold badge in robotics. Should have hired him, then I'd have a robot cashier. My teenaged daughter has gone off to college and I had the shopkeeper's totally unskillled husband fill in for her. Ouch. Lost lots of customer loyalty that day.
That's what I've started doing, hiring towines to do the tedious work really fast that does not require socialization of other sims. The first business I've built is both profitable and popular. It's an art gallery filled with costum art made by Darren Dreamer (I had him working his butt off in "still-life" and "portrait" heaven before OFB came out and kept finished pieces in inventory) and it is run by Darren Dreamer and his wife (forget her name). Darren is all about sales and his wife socializes people. His hired help inlclude Dirk (who is a supburb salesman), Meadow Thayer who alternatly tidy's up and restocks some of the really expensive purchased art, and Brandon Lillard on cash machine. I think I could do better than Brandon though, I hired the townies at the same time because I didn't realize that sims available-for-hire changes on a day-to-day basis. I'm gonna keep checking the want adds and get some more appealing crew
So, does JM actually have OFB or did I just have a super-realistic dream??
