In my view sensory marketing is more of a tool of creating sales rather than consumer satisfaction. Sensory perceptions of course make part of consumer satisfaction as it affects perception of service or product quality and service. why do you think you go to a pub for a bottle of beer , instead doing that in your own home?
Yes it can. Scent, for example, triggers memories and emotions that can affect satisfaction. To put it crudely, you can't expect consumers to return to your hotel if it stinks like a toilet.
Yes. It influences customer satisfaction. As an example in restaurants, based on the hotly served delicious dishes to the neighbors, a particular food item orders increased for a steward by other customers. In a showroom, because of the central AC set up. reduces customer annoyance to wait to resolve a complaint.
