My grandfather is completely senile and paralyzed on one complete side of his body. You could have your daughter wait on the sidewalk...At 8 years old she should be able to comprehend "do not move from this spot".
Geez, all this fuss over a frickin' parking spot. So, what you are saying...with all the ideas offered, your 25 minutes of wasted time is more important than your daughter? I imagine you think even the very thought is offensive.
Suck it up, wait the 25 minutes extra and get on with it!
What sidewalk? Unless I get a HC or close parking spot there IS no sidewalk. You are walking and waiting in the main parking lot. And it's a cheap wheelchair, the brakes are in front so she can reach them, she could bump off the brakes easily. She's 8.
Do you take your grandfather out by yourself on a daily basis, twice a day? Unless you do, you can't possibly understand. So please don't judge. It wouldn't bother me either if it was an isolated event or something I dealt with just once a week for doctor's appointments.
And please don't imply that my daughter isn't worth 25 minutes. I don't know how much you help care for your grandfather, but on a private level I compare her needs to that of a newborn. It's all consuming and it takes most of the day. I have to help her move, go to the bathroom, bathe, dress, get her pencils and help her with her homework and schoolwork because she has fallen behind, get her in and out of the wheelchair to dress and eat, and I also still have two other kids and the house to take care of, and still try to work (I quit one of my jobs, but still work from home part time). Trust me, I stay busy.
