.I understand exactly how you feel, my son is very difficult to get through a parking lot, even with my husband and I together. Never mind when we have his sisters with us! I also have had ignorant people say something to me when I am loading the back of my van after putting him into his car seat first.
I used to engage them informing them that "No, I am not handicapped however my son who is in the car is. Thank you for your concern." I also got a Autism Awareness ribbon on my car. And after a experience very similar to yours, I bought Autism Awareness business cards that I just hand out to those who glare at my sons meltdowns.
