It's like if you were paying for a meal by each minute taken to eat it, then the waiter left your food on the counter for an hour before bringing it over because they were busy, then they charged you for that hour because "it already left the kitchen"
Adding insult to injury caused by their own lack of preparedness.
I’m not paying just for food. I’m paying for the entire dining experience. I also probably have plans after the restaurant that are now delayed or a babysitter waiting at home for me to return. If you not only don’t deliver on a good dining experience but also inconvenience me I should get a refund. In my experience, restaurants generally understand that and I don’t even have to ask for the refund.
Also, it was pouring with rain that night. So they seriously had someone at 3 am, in the pouring rain, shining a flashlight at the license plates of every legally parked car with a valid permit just to try to find an excuse to get people.
The problem I have with parking authorities is fraud. When the meter employee gives me a ticket for a different meter, or when the parking ticket fine is $200 instead of say $30, or when the restrictions are absurd/vague ("You can park here for 2 hours m-f except holidays except 9-11 except in green spots except you have to display the ticket in your window except you need to be 6 inches but not 12 inches from the curb except except except except")...
... then this is the part where I start to suspect I'm not paying for the parking I'm using, but instead I am paying for someone else's large and undeserved profit.
