An elderly woman comes into the butcher's shop and asks, "Could I have a pound of sausages?"
The butcher replies, "Sorry madam, we're right out of sausages."
"OK", she says, "Could I have a pound of kidley?"
The butcher replies, "Surely madam you mean a pound of kidney."
"Didle aye say that?", returns the woman, "Also could I have a pound of sausages?"
The butcher replies, "Sorry madam, we're right out of sausages."
"Oh right", says the woman, "I'll bet you ten, no, twenty that you can't get me a sirloin off that top shelf, without using a ladder."
The butcher replies, "Sorry madam, I'm not a gambling man."
"Why not?" she asks.
The butcher replies, "Because the steaks are too high."
"Oh, then give me a pound of sausages. Please."
"Can you just humour me, madam and spell these words containing the letter F?"
"OK" she replies.
He says, "Furniture".
She says, "f-u-r-n-i-t-u-r-e"
He says, "Flood".
She says, "f-l-o-o-d"
He says, "Sausages"
She says, nothing for a moment. Then nothing for another moment. Then she says, "There's no F in sausages."
The butcher replies, "I've been trying to tell you that for the last half hour."

At first I didn’t get it , until I re read the last bit
