You could be right.
This one time we were at a bookstore buying coffee, I started to ask her something while she was standing writing down something, I asked her three times and she didn't answer, the cashier looked at me with the kind of face saying "Why isn't she answering you?".
Then I'll tell her something and a seconds later she'll ask me what I want when I already told her the answer.
Her only excuse is that she was busy and couldn't answer me, which is fucking bullshit because she could have at least said something like "Shh, I'm busy at the moment" instead if literally ignoring me.
