Dashed if I didn't receive a letter from him this morning! Yes, and what's more, I had to pay sixpence for it, which I'd as lief not have done. It ain't that I grudge sixpence, but what I mean is, why the deuce should I have to give sixpence for a thing I'd as soon not have?
The speaker expresses surprise at receiving a letter from someone, indicating an unexpected communication. Despite the excitement, there is frustration over having to pay sixpence for the delivery. The speaker emphasizes that it's not the amount of money that bothers them, but rather the principle of being charged for something they would rather not have received.
This reveals the character's annoyance and underlying feelings about uninvited communications. The letter, while significant enough to warrant a reaction, is also viewed as an inconvenience that incurs unnecessary cost, highlighting their disdain for such situations.
