Four Americans on the train in Italy

I was on the train yesterday, riding from Bologna to Rome.
Four American tourists were sitting in the seats behind me.

The lady pushing the trolley with beverages and snacks passed by.

I overheard the conversation.

- Anything to drink? Snacks?
- Do you have wine?
- (hesitation)... eh.. yes, I think I have Rosé..
- (no hesitation) Do you have any other colour?
