haneda airport transfer

I bought something for my friend when I was transferring from Hangeda Airport last time. Before I arrived, my friend told me to buy something for him when I was transferring. I was still depressed why I had to bring something for him when I was transferring from Hangeda Airport. But then I realized that my friend would have waited there for me to change planes so as not to delay my own travel time. Most importantly, there were a few shops near Haeda Airport transfer where things were pretty good, but my friend had not recommended them to me. I don’t think the quality of the original stuff is so good.
