Mango Supermarket review: Embarrassment by manager

Me and my friends went to Mango supermarket yesterday evening around 6pm and my friend something funny and we were laughing and one of the staff thought we laughing at him and he went to call the manager. And manager did not even ask any questions from us and he started shouting at us in front of all the customers.. We were so embarrassed by the manager yesterday because we laughed while shopping many people are complaining about the same manager of the same manners also
