Guaranteed money is better than maybe-money too. Most operators will take a guaranteed 8 hours compared to maybe filling a spot later. Taking this to the extreme, many places here sell monthly packages for commuters. The variable hourly-rates is also a form of price anchoring and takes advantage of sunk costs. Look at Westfield's Sydney CBD rates here: https://www.westfield.com.au/sydney/parking https://www.westfield.com.au/sydney/parking Once you pay that first $35 it's not so bad to stick around and spend a bit more. Westfield has a vested interest in this since they run the shopping centre, but other local operators have to compete with this so can't be too much more expensive.
