It's far from the majority of situations (i.e., not the "normally accepted standard" for most people), but it happens often enough that I hear about it quite regularly.

The conditions vary -- including (but not limited to) fickle officers being just that -- and that is a large part of the problem, especially since once the notation is placed on the visa page it's basically back to the consulate/embassy before the next return (if there is another one).
