Accessing Wifi Service with Specific Provider?

[WWGD]

Hi,
Sorry if this is too simple. I was given permission by an employee to access to the Wifi service, using my PC, at a FedEx store,i.e., I will not be using their computers. I thought this would be straightforward: I would be given the key/password and then just log on to the network. But then the employee there said : no, we don't do it that way, then (something to the effect that ): ATT is our provider. What does this mean?

ITs probably this scheme where you log into ATT just like a hotel internet:

and from a business to business relationship:
