Advice Please

I've just started a new job. I start work at 8:30am. To get to work I will need to get a lift off a lady who lives local and who offered me these lifts if I got the job as she drives past my work (as I don't drive and there is no public transport links). Am very grateful.
My problem is that I will need to leave my DC 5 minutes waiting outside school for breakfast club to open.( It opens at 8:00 but the lady who picks me up has to leave for work at 7:55 latest to get to her employment).
There are always other parents around but I feel I'm leaving them alone and worry I'm being neglectful.
Wwyd? Do you think this is ok? Or would you not leave until you had seen DC enter the building? ( Dc 8&10)

Lady lives in the same street as school so I'd only have yards to walk to get to her home for my lift.

How old is dc?
Do you know the parents of other children who get there at a similar time? Perhaps you could ask them to watch your dc for a few minutes.

Could you not ask another parent to keep an eye? I’m torn really as I think a 10 year old could walk to school by themselves so in theory waiting 5 minutes would be fine but then they’re also in charge of the 8 year old

8&10.
I know who the other parents are but I find them unfriendly and unapproachable.

At that age they should be capable of standing in front of a school for 5 minutes. In most parts of the world children much younger than that walk to school by themselves.
