A woman was shopping at her local supermarket where she selected: 2 Litres of low fat milk, 6 eggs, 2 litres of orange juice, A lettuce, half a dozen tomatoes, a 500g jar of coffee a 250g pack of bacon.As she was unloading her items on the conveyor belt to check out, a drunk was standing behind her watching. While the till operator was ringing up her purchases, the drunk calmly said "You must be single."The woman was a bit startled by this, but she was intrigued by his intuition, since she was indeed single. She looked at her six items on the belt and saw nothing particularly unusual about them that could have tipped off the drunk to her marital status. Curiosity getting the better of her, she said, "Well, you know what, you're absolutely correct. But how on earth did you know that?"The drunk replied, "Cos you're so ugly."
