Before the patch I had problems with sims stopping qued commands to go wash their hands. :# Since the patch, once in a while they will get a drink from the faucet, which imo is better than washing hands 20 times a day...gah! I most always have them go to the fridge to get a drink with their meals...I drink soda/water with mine, so they can too. Cuts the times down from them visiting the sink. Most of the time when they get water, they will take it with them to go talk to someone in household, or just stand and watch tv while drinking...I do too. :D
Now, very seldom do I have a sim who has the OCD to wash hands 20 times a day...yay!
