A Day in the Life of a Sales Person

They say that a good sales person has one of the best qualities of getting along with everybody. Hmmm... but it seems like it only refers to customers but dealing with coworkers then that is something different. When you greet a customer once they come in the store, then that is where you see the sales person never leaving their side. Understandable that is their customer. If a customer came back to the store ready to purchase and you have greeted them. Then a few minutes after that one of your coworker greeted them by saying "Oh you are back.". So is that still your customer? Technically I think it is the customer of the original sales person. Though I guess that only happens if both sales people think the same. The economy is down and money is tight with everybody but really should this be a big deal. Why should this be such a big argument? If you have not yet pitch a sale to a customer and just started helping them should it be fair for you to get the sale? If you have waited for this customer to get back to the store and took them back from another associate should you be labeled as a customer stealer? I wonder ....
