You need to be firm when you manage a business. This way people respect you and believe you are not an easy owner to be bullied by customers and competitors. The bully there will be if you have a soft heart easy to negotiate with a discount despite the price fixed. What will happen to your business? Despite you having workers to entertain the customers but because you are known to be a man of soft heart, then the workers would approach you and tell you about the request of the customers for some percent discount. If things like this happen successively, your business will turn bankrupt. You need to be strict with your rules. There is no harm to being called strict than being called soft. Profit is the answer.
