I don't understand why I have to queue 15 people if I simply want to buy an iPhone without anyone having to sell it to me. Do I really have to wait an hour to take one home when it's just paying it and putting it in a bag? It would not be better a box for this type of purchases in which you do not want a commercial to explain how it works or how wonderful it is? It's just that I ended up somewhere else. I do not get it. I'm going .
