Mom’s, do you think its okay to leave your small kids in the car while you run in to pay for gas? what if you lock the door and crack the windows? would you do this or take your kids out of the car seat every time to come inside with you?

It it does then i just found out today as it was the first time i have got a full tank of petrol..lol

The pump stopped working and it started clicking and i thought something was wrong….is there some sort of sensor, or was there indeed something wrong with the pump..?
I feel like a dummy…only been driving 2 years and never got a full tank:D

does anybody know how much these things cost,really dont want to be done over at the garage.
