They are generally more polite now than when that happened -- although the thirds and fourths are still common (and that's with much larger firsts and seconds than they used to have!). And this is a rather different situation; sweets like that are understood to be treats, not free for anybody to grab whenever one wants. I didn't announce that they were off-limits, nor that anyone who wanted could pig out on them ... but a few somebodies sure chowed down all the same!
