The newer coin phones in Britain, which in the cities means most of them,
also have this feature.  However its use in this way is not documented;
you have to figure it out.  Is this a case of expecting people to understand
it, or expecting people not to understand it?

(The button is marked "follow-on call" and the documentation says it is
to let you make an additional call or calls on the same deposit of money.
However, it is also noted that when you hang up you get back the largest
amount of your unused money that can be made from the coins you deposited,
and that you can add additional coins at any time.  Hence, the button can
be used in the manner described for the German phones.)

Of course, this is never a problem in either the US or Canada, because
in neither country do the phones take coins above 25 cents ... not even
now that we have a circulating $1 coin in Canada.

(Well, no phones that I've ever seen, anyway.)
