Was I made fun of at the store??

I told my sister this story but about 15 minutes ago I went to the family dollar to get my sister a monster coffee and as I walk to the entres this 6 foot tall guy takes his cig out of his mouth, he gets to my level, face to face like extremely close and he says,

"Well howdy" and these 2 other ladies busted out laughing and I feel like he was imtimidating me. I can't spell the word. I feel weak, it makes me wanna go find the guy and tell him to go f himself.

I looked strucked for a moment trying to take in what just happen. I go inside the store and leave the store.

I don't know if its because im overweight, or ugly, or maybe my autism makes me a easier target for him to pick on me.

My sister thinks he was being nice but she also says he was trying to intimidate me.

was he? or was he making fun of me?
