I am addicted to diet pepsi...I admit it...meaning my battle is half over...haha

In a recent flight from SFO-ICN, I had asked for my fourth diet pepsi in a row; I was doing work and I had to be awake and I was getting a lot done (the pepsis were helping).

The FA gives me this strange look, are you serious type look?

Now, I am sitting in F class, I don't care if I had asked for the 100th pepsi...why give me that strange look. The service sucks, food sucks...I will never fly F class again, unless of course they give it to me for free.
