Deadpan Conversations With Shop Sales Staff, Vol. 2

Scene: A pub, early on in the evening. Very few customers about.

Barmaid: Hi. Are you being served?
Me: Not yet. Can I have a pint of San Miguel?
Barmaid: What would you say if I said 'No'?
Me: I'd say, 'Can I have a pint of Kronenburg?'

I'm hoping this will eventually become the definitive collection of every conversation I ever have. That would be a worthy enterprise.
