It was noticed that there were differences in how the Autistic and the Neurotypical shop.
Aut has a pre-planned route and a mental list that she follows rather strictly.
Nert roams counterclockwise, skips some aisles but might backtrack and go to the ones she missed (maybe, maybe not); touches everything and some items she picks up to keep but changes her mind and sets the item back in the nearest open spot (not in its correct aisle or place); hums and sings to herself and frequently talks to strangers.
Aut doesn't touch things unless she has a serious intent of possibly purchasing as she fears germs, chemicals, poisonous substances, as well as cooties and ickies. Once an item passes from her hands to her cart, she is committed to buying whether positive or negative for better or for worse.
Aut is very quiet. She does not hum or sing to herself but often has to remind herself to not talk out loud as she is thinking and remembering as she shops.
Aut rarely talks to the strangers unless they start it first.
