Some of the trendier merchents have Square in my neighborhood. I'm in NW Maine. I just bought some alpaca wool and the nice lady swiped my card through a Square device attached to her phone. The pie lady takes Square too. I think the new coffee shop, down in the village, now has a real merchant account, but they did use Square. I've never even seen Venmo.
Err... I'm old, but we have hip and trendy tourists?
Ah well... Another anecdote for ya.
