Beer with a straw

In Kazakhstan girls who order beer gets it served with a straw.  I never quite understood this...is it more lady like?  Do they think the pint glass is too heavy? Will it makes us cheerful more quickly?  or is it just the way it is??  :-D

This picture was taken at a Thai restaurant where we passed time with a really yummy meal waiting for our 3am flight...

So long Kazakhstan!  I've had a lovely visit!!
