Laners just thinking they know best. Sometimes it's true, other times it's not.
Same goes for ganks. Saying 4 min in to game you need a gank bot Lane when I'm just starting my top side buff... Maybe you want a gank, you don't need it though (I'm complaining because I was an idiot and went to gank after buff anyways and then the adc didn't go in and I lost double buffs for nothing, was on tilt and thought I'd best let others make the call for me - dumb decision, finally got off my streak by being assertive).
The jungler really gets full decision of what objectives take place in laning phase. I think complaining about objectives/ganks during early laning phase is just the sign of a bad player (you can't handle Lane on your own so you say it's the junglers fault for not helping).
That said, there are times we score a double kill bot Lane and mid Lane is pushed, and the jungler decides to buy or something, sometimes your teammate has a better game sense. Would love to see people just start communicating, ask instead of order, and actually take other's advice.
