The two Cambridge fellows seemed to find something to laugh at in this, and one of them said I didn't mind being taken in, but I didn't like being taken in and done for.

I suppose he thought this was a joke.

Some idiots can grin at anything.
I told the hotel people I should certainly not pay for attendance, as I didn't consider I had had any.

The waiter said very well, my boots would do as well, and they would keep them till I settled the bill, and they had no time to stand fooling about with a whipper-snapper.

Of course I had to shell out, as my boots were worth more than the whole bill--although my bootmaker has taken me in pretty well over the hobnails.
