How did the narrator learn to distinguish between 'a flask' and 'a thermos'?

Answer:

There was a time when the narrator went to buy tea bags and a 'flask'. This is when he came to know that the thing which he was looking for was actually known as a 'thermos' and 'flask' was something which was used to store Whisky. The reason for the narrator having limited knowledge on the subject was the fact that he hadn't consumed whisky till then.
