DO NOT make sudden moves toward me

I would react as a threat and pepper spray you

So I was packing my grocery at the exit of Harris Teeter, this imbecile came over, make a sudden move toward me and stick his head close to me, I was startled and reach for the mace.  Luckily for him I stop.

I asked whether he wanted the cart I was using, he said "what was that?" as if he doesn't understand me, followed by a stupid laugh.

I figured it is one of those hillbilly imbecile never seen an Asian before and assumed the stereotypical of Asian doesn't speak English.  I just roll my eyes.  I just don't have the patience to deal with imbeciles like this anymore.
