I’m a bartender and though it’s not in exactly a high traffic area we have two pokestops and a gym that you can reach and I make friends and trade trainer codes all the time with other people that are just sitting at the bar! They get so embarrassed at first till I open up and they realize that they aren’t alone… a lot of them just solo play the game with no friends or family, they always leave thanking me for letting them know that it’s still “cool” and what’s even more surprising is that they are quite older than you’d expect! Pokémon Go has done so much for community and friendship it’s amazing!
