That’s a pity Paul, but that’s life. 
1/2 pint is pretty small ca 0,236 L
And a pint is ONLY 0,473 L
A problem

A flower vase?
Old beer drinkers are inventive…hehehe!
No, only a joke as usual.
May be you find a pint glass, if not ask the neighbours and tell them

Dont drink from the bottle please, because the acid is strong.
But if you are alone nobody will mind if there is some burping.
(The more burps the better the beer)
And at last you can always tell Debs and Charlie
its only caused by that strange brew from Germany,
and I (Franziskaner) am guilty and take full responsibility!
