I had supper this evening at the Blarney Stone (Water Street/Carrall Street).
It's a big pub ... they have lots of room in the back and upstairs.
But everyone was sitting in the front, near the open windows and at the bar.
I watched this woman pour her beer into a water bottle, which she then put into her purse before she left.
When she and the fella she was with left, I moved over to their table as it was on the patio. Other than a couple people stopping to ask for spare change, it was a nice spot to be.
