A lady calls a Dentist to inquire about the cost for tooth extraction.
Dentist: Rs 850 Ma’m.
Lady: Rs 850!!! Too much! Don’t you have anything cheaper?
Dentist: That’s the normal charge, Ma’m.
Lady: What if you don’t use any anesthetic?
Dentist: That’s unusual, ma’m but can be done and will cut the cost by Rs 400.
Lady : Ok. And what if you deploy one of your trainee-dentists to do the extraction, without anesthetic?
Dentist: Well, I cannot guarantee professionalism and it also would be painful. But the price could drop down to Rs 150.
Lady: Hmm! What if you make it like a training-session, like one of your students does the extraction, while the other students watch and learn?
Dentist: It’ll be good for the students but quite traumatic. And I can pay you Rs 200 for it.
Lady: Now you’re talking! Ok, it’s a deal.
Can I confirm an appointment for my husband for tomorrow then?
