If you're
travelling abroad, these are the two
phrases you
must learn in the
language of any
country you visit:
Two beers please.
And:
My friend here will pay.
Needless to say, this works best if you're travelling with someone who doesn't speak the language.
Some sample phrases to get you started:
German:
Zwei Biere bitte. Mein Freund hier zahlt.
Spanish:
Dos cervezas, por favor. Mi amigo aquí pagará.
Australian:
Two beers, Mate. And the drongo sitting next to me will slip you a rock-lobster.
