Meinwen narrowed her eyes at the pint of Guinness she'd just been served. "Any why, pray tell, is the Guinness green?" she asked.
The barman stood back, grinning so hard it looked like his jaw would drop off. "It's St. Patrick's day," he said. "All the beer's green to celebrate."
Meinwen pushed the glass back across the counter. "Then I'll have bottled beer instead," she said. "I'll not celebrate a man who was sainted for killing pagans."
"Pagans?" The bartender wore a bemused look. "Nah. He got rid of the snakes."
"Aye. Snakes being the worshippers of non-Christian gods." Meinwen stood. "Forget the drink."
