I have to admit that I haven't been to the park this season to purchase anything quite yet, but how is this working? Especially with speed. I have visited 6 MLB parks this summer, all with cashless, and the time required to finish a simple transaction for something simple like a beer or lemon chill feels like it has increased dramatically. In fact in one ballpark, the vendor had to go as far as to hold the device over his head, seemingly to get connection. It's tough. I want to love this, but infrastructure has to be increased to make the customer experience better. Just my 2 cents.
