For the past 2 season's i haven't expected a single blue from jungler, i don't even ask if i could have it. I have no idea why some people consider it yours if you are mid.. I can understand the pro scene but yoloq..
I completely understand if champions like these want the blue buff for themselves:

But if your jungler is one of these
or any other manaless jungler.... It is a bit wasted on them, tbh. Level 7 Rek'Sai myself, I take the first blue buff in game because of gold and experience. Afterwards I give every blue buff to my mid laner. Because I really don't have use for the mana.
yoloq
That made me LOL when I noticed it.
when your mid and need blue then remember you have an
