A not so brief swing by the grocery store

Yesterday I let James play with the keys as we grocery shopped.  I put him into the car and shut the door before getting into the front seat.... you can probably guess where this is going. In the seconds between putting him in the car and getting in myself, he figured out how to push the tiny lock button. Initially he sat there continuing to jiggle the keys as I pantomimed him pushing the button again and tried to will him into unlocking the car. No luck. Who do you call when something like this happens? It was snowy, but not freezing cold, was it an emergency?  Not that I could do much calling myself -my phone, wallet, and the spare keys were all sitting on James' lap. It seriously took me at least 5 minutes to grasp that I really had locked my child into the car. I ran into the store and the cashier, without missing a grocery swipe, used her free hand and calmly called 911 and gave them the address (this must not have been the first time this has happened.) As I stood in the snow trying not to ball as my baby wailed at me thru the window I felt like such a terrible mother. Well, the fire truck came and produced a coat hanger and 2 wood shims (that's all they can have these days since they damaged too many cars with the real equipment, but they still get the calls so...) After they took turns working at it for a while with no luck, just before breaking the window, someone produced the number for "Pop-a-lock." Turns out if you have a child or pet locked in your car they'll come pop the lock for free. A bit of information I, and the fire department, was glad to learn. While I'm sure James has already forgotten this incident, I'm pretty sure I'm scarred for life.  Randy suggested I recreate it so I could post a picture. I'd really rather not, if you don't mind.
