Hi, I love grocery stores so much I want to open my own store where I have lots of food.
That sounds like a real challenge! My favorite grocery store is Publix. Have you ever heard of it?
I love Publix. I just went on vacation to Florida and went to publix alot. 
Nice. Publix pretty much dominates Florida. One of the most beloved things Publix offers are the famous Publix subs A.K.A. "Pubsubs."
I'm pretty sure I saw a Publix in Polk County in Bartow
I don't doubt it, they are all over Florida. It is routinely ranked as one of the best places to work in the whole nation!
I am moving near Austin, the capital of Texas soon and HEB is the main store
I've never heard of HEB. That being said, I haven't spent much time in Texas. Do you like it there?
ITs nice! HEB is like Publix, they are in almost everytown except they are only in southern texas and northern mexico. 
Oh that's neat. I wasn't aware of any grocery stores that were both in the US and Mexico.
