I worked briefly at a paint and plastic furniture depo where we sell massively every day and that has taught me on how to access customers and then based on that you know what type of person they are and determine the best way to interact with them and not sound conflicting to them .
Above all customers are always right but to an extent and if we know this extent which I have learnt then we know that there's a certain level where we would have to stand our ground and explain to the customers and make them understand
