A number of years ago when we lived in Walnut Creek CA, we went shopping at a local grocery store for a few items. At the checkout counter, we put the items on the conveyor belt and as they were being scanned I commented to Bob about getting pop. The young clerk at the counter was surprised and wondered what I was referring to. He knew it as soda. He asked me if I was from elsewhere like the MidWest. No, I am not though some of my family roots are from Nebraska.
It is interesting how people will say words differently from what you personally will do. Friends from Illinois would say “Sol-mon” for Salmon (S-al plus mun). Or hambooger for hamburger. We are just different. If you want to know how different and what those differences are, here is an article on the different dialects found around the United States.
