My restaurant has a total of two waiter stands and seven garbage cans and still the wait staff can't seem to fulfill their assigned function in clearing dirty dishes. I don't dine out as often as I would like because I can't stand to watch the wait staff glitch the way they do. They collect the dishes but instead of using all the posts they are meant to, they just place the stack of dirty dishes on the tables to which guests are eating at.
Second to that, I have three people on my wait staff and two chefs who are set to cook carefully, yet, orders come up like once every 3 sims hours. It makes no sense the lag from when sims are seated at their table to when they actually receive their food, and that's with any cook setting. I get it's supposed to be a challenge, but it isn't. The way Dine Out works is just frustrating as a guest and playing as the establishment's owner.
