'Want the receipt?', um no!

I went to get some chinese cabbage for the won ton soup my mum was making today. And when I went to pay the woman at the till printed off a receipt (as you do). But she had forgotten to get rid of all the previous receipts. So the receipt was this veeeeeeeeeerrrrrrrry long piece of thin paper. So the woman asked me whether I wanted the receipt. I looked at the receipt draped over the counter and trailing all over the floor. I looked up at the woman. I said, 'um, no'.
