immediate gratification 

Someone who expects you to drop everything you're doing, to cater to their bullshit needs. They feel what they need you to do is more important than anything you could possibly be doing. Most are selfish assholes with zero consideration for anyone but themselves. Plus, chances are they haven't even tried to do it themselves and are just too damn lazy and inconsiderate to try.

If a child exhibits immediate gratification when asking for something, their sense of entitlement will grow worse with age. Never just jump up to do what is asked of you, make the person or child waits until you are done with what you are doing, showing that your time is just as
important as theirs.
