Ehh maybe. I mean, it was a three hour show and I don't carry coins any more. So that would have been ATM -> go to a store and break a twenty -> put in a few bucks -> remember to go out at intermission and put in more money.
Paying by phone is a step up from that old world; I just want it to be one tap, not a whole sequence that tries to upsell me on a monthly pass or establishing an in-app "parking wallet" or whatever.
Not carrying coins is your own fault, not the system's. You can't refuse the analog solutions and then complain the digital ones are too digital.
