As I had been instructed, I said, pleasantly,
"Good morning and welcome to B & Q."
"Nice children you have there. Are they twins?"
The woman stopped yelling long enough to say, "NO, they ain't effin twins.... The oldest one's 9, and the other one's 7, why the hell would you think they're twins? Are you blind, or just effin stupid?"

I replied, "I'm neither blind nor stupid, Madam... I'ts just a little hard to believe someone actually shagged you twice?!.... "Have a good day and thank you for shopping at B & Q."

My supervisor said I probably wasn't cut out for this line of work.
