Shopping For Rubies

I spent my day shopping for rubies, Walked all day until my feet were sore. To find the perfect one, But it had to be in a bargain store. I bartered and fought, Throughout the whole day, With the clerks left and right, And to their dismay. I only had thirty bucks, in my pocket you see, But I wanted a good one, Can you lower the fee? I was thrown out of the stores, Like a poor old pauper. And the words they used, Were far from proper. I shall try the next street, the next block, and then, Perhaps they will have mercy for everywhere that I've been.
