Does this sound good for a lemonade stand? Would you stop?

We are selling full plastic cups of lemonade or iced tea with ice for 75 cents, and choco chip or oatmeal cookies for 50 cents each. We have large, colorful signs, and everything will be covered under an umbrella. We will probably be there from 8-11. Me and my friend are doing it just for fun, not so much for the money. We are both 14, and look respectable and i live in a good neighborhood where we will be selling. We have signs on busy streets nearby. Thanks!
