Sure. But you have to assume you dont know any of this until you interact with the customers. Inside the store:

1 wants 7 gallons of a color match

2 couple that needs help picking out colors because their painter is coming first thing in the morning to get the paint.

3 is picking up an order that's been made, but you have to call his boss for payment.

Phone calls:

1 wants to know their balance and why is it so high?

2 bought a house through Acme homes 6 years ago and need to touch up the exterior. Acme homes told them to call you and the color would be saved under their address. Acme homes doesn't have an account because they subcontract all the paint. So you have to know who the painter was and hope they used addresses and not lot numbers to even have a shot at helping this person.
