Do you think I am banned from that Starbucks or was i stopped because of the coca cola with me?

So in Starbucks of Church Street of our city Bangalore in India, where I visit quite often l entered there while drinking a coca cola and having the bottle on my hand. Suddenly a staff said excuse me and stopped me and said some words like "Not allowed" and "Outside". Yes I couldn't hear her properly as I was wearing earphones but I guess she said "Excuse me. You aren't allowed to bring any outside drinks". She also mention that she said it last time but I don't remember or maybe didn't hear it due to earphones again and entered with the coca cola bottle in my hand. Is it normal for Starbucks staffs to stop someone just for entering with a coca cola even though it's non-alcoholic and harmless? Do you feel I am banned from there and might still be stopped next time even if I enter without any outside drinks?
