re after a great
deal of private fumbling, her back turned to them, she produced the two
much-crumpled L5 notes.
"The steward ought to have something too," said Mr. Twist.
"Oh, I'd be glad if you'd do him as well," said Anna-Rose eagerly. "I
don't think I _could_ offer him a tip. He has been so fatherly to us.
And imagine offering to tip one's father."
Mr. Twist laughed, and said she would get over this feeling in time. He
promised to do what was right, and to make it clear that the tips he
bestowed were Twinkler tips; and presently he came back with messages of
thanks from the tipped--such polite ones from the stewardess that the
twins were astonished--and gave Anna-Rose a packet of very dirty-looking
slices of green paper, which were dollar bills, he said, besides a
variety of strange coins which he spread out on a ledge and explained to
her.
"The exchange was favourable to you to-day," said Mr. Twist, counting
out the money.
"How nice of it," said Anna-Rose politely. "Did you keep your eye on
its variations?" she added a little loudly, with a view to rousing
respect in Anna-Felicitas who was lounging against a seat and showing a
total absence of every kind of appropriate emotion.
"Certainly," said Mr. Twist after a slight pause. "I kept both my eyes
on all of them."
Mr. Twist had, it appeared, presented the steward and stewardess each
with a dollar on behalf of the Misses Twinkler, but because the exchange
was so favourable this had made no difference to the L5 notes. Reducing
each L5 note into German marks, which was the way the Twinklers, in
spite of a year in England, still dealt in their heads with money before
they could get a clear idea of it, there would have been two hundred
marks; and as it took, roughly, four marks to make a dollar, the two
hundred marks would have to be divided by four; which, leaving aside
that extra complication of variations in the exchange, and regarding the
exchange for a moment and for purposes of simplification as keeping
quiet for a bit and resting, should produce, also roughly, said
Anna-Rose a little out of breath as she got to the end of her
calculation, fifty dollars.
"Correct," said Mr. Twist, who had listened with respectful attention.
"Here they are."
"I said roughly," said Anna-Rose. "It can't be _exactly_ fifty dollars.
The tips anyhow would alter that."
"Yes, but you forget the exchange."
Anna-Rose was silent. She didn't want to go into that befo
