Working the property VS working the customer

I work hard for my customers. Most real estate agents will show a customer 1 or 2 apartments and that's it. They work the property. They will show the same 1 or 2 apartments over and over again until they rent it. They will show the 1 or 2 apartments 100 times if they have to. I don't do that I work the customer cause I want a relationship. I will show as many apartments as it takes until we find something they like. Maybe in the future they will want to buy something from me? I love referrals!
