I’m surprised they recommended an iPhone of any kind. I worked for them from iPhone 4-6S and almost every employee and manager was extremely biased toward Android. I doubt that’s changed.
I would also imagine every Verizon store likely is different though. I have six Verizon Stores in my city, two which I frequent and I feel the employees are different at every store based on what they recommend from experience and use personal use for a phone.
