The tangibility of each performance cue. Because of the intangibility of services, most consumers look for tangible evidence to describe the service encounter For example, the large effect of overall value on word-of-mouth intentions(relative to quality) might be due to its relationship with price an extrinsic and more tangible cue.This relationship with price may cause value to be more salient to consumers because it involves give and get components whereas quality involves only the get component As a result value has a stronger effect on word of mouth intentions because it is a more tangible cue experienced during the service encounter
Tangible may also play a role in the effects for the room service and housekeeping employee cues. Of the employee cues we examined, only room service employees deliver a tangible good(food) along with intangible service. The increased tangibility may explain why the performance of room service employees has an effect on perceived value and no effect on perceived quality. For housekeeping employees, hotel guests may evaluate performance in items of service outcomes(i.e., a clean room and hotel) rather than the service process(i.e., friendly housekeeping employees) This focus on tangible dimension of housekeeping performance might explain its direct effect on word of mouth recommendations
