Dilemma: You are watching a Rugby World Cup game at a stadium and you fancy a beer, but you don't want to take your eyes off the action.

Do you get out of your seat and go and find a concession stand somewhere? At this year's tournament in Japan, you don't need to.

"I walk around the stadium pouring out beer for customers who want it," 18-year-old Mio Ishimori, who is working as a beer hawker at the Rugby World Cup, said before Saturday's quarterfinal between New Zealand and Ireland at Tokyo Stadium. "The customers will lift their hand if they want to buy a beer, and we go over to their seat and pour them one."
