You can't call it a Black & Tan in an Irish pub since the Black & Tans were known for their police brutality and attacks on civilians.
Now a Half & Half (ahff and ahff) would be served with a smile.
Seriously? Is that the new PC way of asking for it? The bar I used to go to was an Irish Pub and called them that.
Or am I missing the sarcasm? I guess I need a Half & Half, LOL!
