Why were they all women?

she charges me £54 and forgets to charge me for the £52 gift set I was buying my mam.
A similar thing happened to me in M&S in the summer. I bought trousers, a top, a handbag and a coat. The bill came to £70 (half of what it should) because the assistant forgot to charge me for the coat.
