At a sign stating "10 Percent OFF Today Only" was posted at the camera counter at Orson's Department Store. The clerk at the camera counter suffered a heart attack while on duty. After the commotion had subsided, a well-dressedshopper walked behind the counter and cleverly changed the number on the sign from "10" to "30". This imposter sold 10 cameras to customers in a few minutes, pocketed the cash from those who paid cash or made down payments in cash, and fled. The manager, finally realizing that the camera sales counter was unattended and seeing the changed sign, began to smell a rat. She ran to the store exit nearest the camera counter looking for customers with bags bearing the camera department's distinctive snapshot logo. She stopped four customers at the exit who were happily leaving the store with their "discounted" expensive cameras. Under these circumstances:

A) the customers lose as they dealt with an imposter

B) Orson's loses under the doctrine of apparent authority

C) the customers win under the doctrine of implied authority

D) the customers win under the doctrine of ratification by Orson's failure to stop the other six customers
