Nope, it's not hot. It's ranges btwn 68-80 degrees during the day. The weather isn't really a factor (although if it WAS summer, it would've been, because that baby wouldn't have lasted an hour in the car during summertime).
For all she knew, this valet parker could've been a child molester, sexual predator or even a serial killer. Any Joe Blow off the street can get a job parking cars....it's not like there's some big background check being done. She literally handed her child over to a virtual stranger, and ANYTHING could've happened.
What's worse is that there are people commenting online on azcentral.com and directing negative comments to the valet parker!!! There's a lot of people saying things like the valet should've never called the police, that she has right to do what she wants...blah blah blah
