"Would you like milk with your black coffee?" Said the nice girl in the cafe at Poppit Sands, West Wales
"Ooops!" she said as she embarrassedly realised her mistake.
"Can I have a straw please" I asked.
"Certainly" she said "would you like one or two?"
"One would be fine " I said.
I thought it would be more useful for my son's 7up than my black coffee after all.
