“It’s really simple, there’s actually a glass really close to my house right now!” She takes her phone and game on the go, searching around her house and the garbage until she discovers a glass of Chardonnay under a tree, and then another across the street. Find a glass, take a sip, set it down, repeat. That's all there is to it.
On the downside, you don't get to keep the Chardonnay the same way users get to keep their Pokémon. On the other hand, Pokémon aren't real, there's no training your glass of Chardonnay, and this game is played with wine. Point, Blizzard.
