Yup.
Once sold a pair of specs to the Dad of 'Combat Barbie'. And he wanted a discount because his daughter had a medal.
No, he didn't get one. The price is the price. I don't care who your daughter is, or what she does. Because you're the speccyblindo wanting the discount, not her. If she asked for a discount on her specs, I'd have spoken with my manager. If she asked for a discount on her specs in the way you had sir, I'd have told her to bog off and all.
