Item 10 item 10 keith liked how the dry cleaner down the street washed and pressed his clothes, but he found the repeated phone calls from staff about his finished laundry annoying. he began to think of the whole place as annoying, which is a function of the aspect of services

inseparability aspect of services refers to the market phenomenon where consumers would let their judgement for the quality of the overall service is influences even by smaller part of the service.
Other example would be when a customer believe a certain barbershop is excellent simply because he has a pleasant conversation with the barber, not because the quality of the haircut per se.
