It should have been put coins in a slot.
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.
Or use your card on the machine. We had that for a while, but then these stupid parking companies started to get traction.
