I agree.
It is not very often I don not have my little ones with me and with a 17mths old, 2.5yr old and a 3.5yr old it would be much more dangerous to get them out then leave them in the car.
I always use the closest bowser to the doors and they are never distressed or upset when I go.
If only have one then I tend to take them in (very rare occurrence)
