Game Restaurants completely Broken after this patch

I just built restaurant
(or well in my mind its more of hotel)
in old new neighborhood of henford

and all sims keep changing to swimwear (not restaurant attire)
and chatting interrupting and crowding the place
+ one of the waiters apparently doesn't know how to use toilet so i keep filling their needs

but all the actual restaurant functions otherwise work all fine orders come quick and all

i just don't understand why the lot gets so overcrowded its really irritating

they really should let us set customer limits
