BULLSHIT! I took an appointment at 8.30pm for a display broken on my iphone 6. I came at this Apple Store, I wait 20min and the girl told me "it's too late you have to come back tomorrow". That's funny but tomorrow I have to do a roadtrip during 2 weeks, this is why I took an appointment today! So dear Apple, where is the sense to take an appointment with your store if it's too late to do anything??? And where is the sense to ask what is the problem when you take an appointment, if when you come this is too late for the reason I noted???? Apple Stores in the US are the worse things I saw in my life!
