But med student should learn to choose their battles and learn to start sucking it up sometimes, it's the best way to become a successful doctor. If they don't learn soon to start sucking up the bad things of medicine, guess what? They continue their whine-a-thon in clinicals (ooh mean Mr. Dr. made ME do some scut work! The HORROR! Can't you see I am a walking god and the hospital have staff for this??!!), then continue their whining in the internship, residency and then become the grumpy, unhappy, miserable doctors everyone hates and ends up getting sued only because they were rude to a patient.
I have seen several friends that are like this, they are my friends and I like them for hanging out but the higher ups have a poor image of them stating they are lazy, annoying and don't want to hire them. Higher ups also don't like med students that have a god complex that think they are too godly to do any scut work (ej. they are just lazy and don't want to admit it). Even in med school you are making future job contacts while rotating hospitals, many doctors will remember your face and remember if you had an inert laziness and will not want to hire you. In some fields every doctor knows eachother and just like in that episode of Seinfeld where Elaine can't find a doctor to treat her because her medical records have a bad note in them, word can spread quickly.
Instead of whining about taking blood sample X, you should be infinitely grateful you are honing your blood sample taking technique while you have a higher up supervising you because once you graduate, you are all alone and whatever you didn't learn while you could, you are stuck with it and it's harder to do the scut work the higher up because you know have someone else that does it for you. In many cases nurses ask me to take the really difficult blood and IV lines because they couldn't, they expect you can do it with your eyes closed everytime. Med school is the only time you can do this, you don't want to be that weary intern that runs and hides in a closet when a woman giving normal birth shows up in the ER door.
If you are positive from med school stating the good stuff weighs more than the bad, you will have a very happy career and will go to work with a smile in your face.
