As a tall person I cannot offer to reach something on a high shelf for a stranger, yet if they ask me I must oblige. This is the law of the giants

(Short here) thank you for your lovely laws.

As a 6’2 person in sales who spends a lot of time in stores, I solemnly nod my head in agreement.

I also pull items to the front if all that's left is on the back of the shelf, in case the next person doesn't have as long a reach as I do.

6'2". Can confirm.

As a short person I will absolutely not mind if you offer, but alas, I cannot speak for all short people.

I like the non-verbal asks from strangers. Giving the “uppy” sign with both arms extended

Always happy to use my tall powers for good

I am guilty...have summoned a tall person 4 or 5 times at grocery store. They were very positive in attitude.
