The first Wal-Mart (or Walmart) outlet that I have been to is the one located on Keamoku Street, Honolulu (Hawaii) - just a short walk from Ala Moana Shopping Center.
I remember having been very exited at that time even though I have been to similar retailers like Carrefoure (French), Tesco (British retailer), Audi (German retailer).
I have read a lot about Wal-Mart in text books - its humble beginnings, the story of Sam Walton (the founder) and his noble intentions for starting the business (providing affordable goods to not-so-wealthy people), etc
What really caught my attention was the lingerie section - multiple sizes and colours;-)
