I would suggest that average time and cost to park is what you should compare against, i.e what is the normal amount of time you would have allowed to park and walk to the restaurant? Add the cost to park. That would be the basis for comparison for the cost - convenience tradeoff. Not best case where nothing goes awry. I get the urge to want a do-over (credit for both parking charges), but I don’t get the double-credit for hassle. Parking in Hollywood is a pain with or without an app.
Your offer for a credit is a nice gesture, but I think the following is more fair:
A refund of $14 ($6 for my SpotHero charge [receipt attached] and $8 for the parking meter [receipt attached]).
A $20 SpotHero credit as a token to compensate me for the hassle of looking for another parking spot, the stress and embarrassment of being late for a business meeting, and the time it has taken for me to work with SpotHero to correct the problem.
