What did we do wrong?!?

me and 2 friends had a lemonade stand, and we only made $8 total in 4 hours!!! wat did we do wrong? it was a very busy street. many joggers and bikers. we tried the lemonade and it was DELICIOUS. the customers that actually came liked it too. $3 came from my dad... the lemonade was 25 cents. the cookies were 50 cents. are posters were amazing! in the neighborhood, its against the rules to tape the flyers to the stop sign... so we couldn't advertise it.
