When I am small kid I really loved thumbs up because on those day that drink is only drink that refreshes the body and mind but now a days thumbs up is not good and taste worse The strongness of thumbsup has gone that was the key point of thumbs up every one wants strong drinks and specially for youngsters they all love strong drink.
I think that was the key reason of decresing demand of thumbs up and increasing demand of coca cola and pepsi I complitely trust the product thumbsup and I know the same days has comes from the past and demand increses of your product. My openion is to you that increase the taste and make the thumbs up strong.
Thankyou
