Regional preferences, experiences and habits guide our approach to many products like food and drink. Think of Soda in the Northeastern US, Pop in the Midwestern US and Coke in the Southern US. All are names for the same product.
Depending on where you live in the Northeast US you enjoy a Hoagie, Hero, Sub or Grinder. Would you be getting the same or different food when you order? Often, you would get the same food with a different name.
