Who are these tits who complain about Marks and Spencer ?

I am really confused why people are complaining about paying extra for larger bras at Marks and Spencer.

Surely bigger bras require more work on the stitching and more material. In addition they require more packaging and no doubt have a higher transportation cost due to the fact they take up more space.

Nobody complain at paying more for an extra large drink or an extra large bar of chocolate, so why do people feel that their extra large bras should be less ? I know I have had to pay more for larger shoes in the past, surely this is the same principle ?

I wonder whether these more fulsome ladies would prefer to be flat chested and pay less ?
