Did I order Five Guys in a good manner?

Hello guys, I am a non-native speaker and live in Edinburgh. I walked in a Five Guys last Sunday and was looking at the menu on the top of the wall. I always feel hard to make decision, so I was looking at the menu for a one minute long. There was no customer in the queue at the moment. When I was thinking, the cashier kept saying hello? hello? hello? And I felt a little bit nervous and panic, so I made a quick decision and said: Can I have a little fries, please? The cashier said: no hello. So I gave a hello awkwardly, and I added: I wanna a spicy one (cajun). And the cashier said: I wanna go home. I feel uncomfortable but I am not sure if I make the cashier angry. Did I order impolitely?
