Farewell Madam, can we get rid of Miss, Ms and Mrs too?

They mightn’t pay the new Doctor Who as much as a man but at least she doesn’t have to choose between Miss, Mrs or Ms.

I am quite certain the young man at the supermarket checkout was being extremely polite when he called me “Madam”, but I felt as if I’d aged two decades while he scanned the frozen peas.

The term of address, respectful as it was meant to be, also cut dead any hope of conversation. What could “Madam” possibly have to say at the checkout when she’s passing through on her steed?
