You wont get the service that I offer anywhere else so please don't compare in the hope of a discount.
If you are considering asking for a discount then I'd love to offer you the advice of looking elsewhere, so that you can save your time and the embarrassment of rejection. You will not be entertained and requesting me to change my mind will only reinforce my decision. This suggests that you are not willing to accept when someone says no. I call it a red flag, my partner would use the phrase trying to push the tip in.
