Ever since I moved to Alabama, Publix.
When I was still in Mississippi, it was always either Kroger or Walmart. However, there's not really a Kroger near where I live and the Walmart is further away than the Publix.
I don't eat out much. I do get fast food sometimes. I last got some from a Jack's and an Arby's a few days before that, and I did eat at McDonald's a good bit when I went back to Mississippi during the Labor Day weekend, but that's unusual for me.
My school canteen. Horrifically overpriced, but I buy it anyway. I refuse to accept there's another place who sells two dim sims for $3.50, that's horrendous. But I'm hungry, I want food, and I will part with my precious money for hot food on a cold day. Then I'll regret it the next hour and then rinse and repeat.
Also, $1 hash browns at Hungry Jacks, gimme that free greasy goodness.
