Recent innovations:

Flat XLB Policy: similar to an LCD manufacturer's dead pixel policy, restaurants should have a flat XLB policy where you get a refund or another batch made if a certain proportion of your xiao long bao (steamed pork buns) come out flat (i.e. the inside juice has leaked out through the wrapper). Because batches are usually 8 or 10, the most likely policy is going to be 0 or 1 / batch.

Inverse Costco Effect: when buying something in bulk is more expensive than buying in smaller quantities. (e.g. a whole pie sells for $12, but individual slices, closer to a quarter of a whole pie are $2 each)
