The bottom line is that there will probably be some growing pains with an all-cashless system, both on the part of employees and fans. But once everyone gets used to it, things will be fine. I don't go to many games (don't live in Milwaukee, so I haven't specifically been to a Brewers game in a couple decades, probably), but I enjoy not needing cash. A decade ago, I wouldn't have liked being forced into using apps for tickets (credit cards for payments have always been great), but it's 2021 and smartphones/mobile internet are much more reliable and ubiquitous, so I think it will be fine. Now if you want to argue that the elimination of print-at-home tickets is unnecessarily restrictive for those who want to gift/share/sell their tickets, that's a different story.
