Pizza Hut is to remove all self-service salad carts from its 440 restaurants in China. Up to now, customers were permitted just one trip to the salad cart, but these restrictions have led to ingenious Scooby snack-style stacking of CCTV Tower proportions. The chain, the first to introduce pizza to China in 1990 and pizza delivery in 2001, claims that the move is part of a general menu expansion, but it's surely down to salad cart abuse.
I’d still call that self service, just putting something there to discourage the behavior.
I’m thinking of this more like going to a self-serve frozen yogurt place. I know at the end it’s by weight so I always get a more reasonable amount of soft serve and skip most of the overpriced toppings. If it was whatever I could fit in the cup, holy crap I’d be getting a small size cup and loading it up with as much as I could managed to.
One where someone is there to check weight/etc as you suggested.
