If your happy with your daily takings, why are you concerned about others? Business is business. If you have worked hard, built experience & are happy with £6.50, no one else's opinion should count.
Your in business to please yourself, not worry about local competition & how much you might upset them. Your not running a charity or doing it out of the good of your heart. In the "current economic climate", you have to look after yourself. Selfish? yes. Should you care? hell no!
Would you rather keep charging high & plodding along, losing a few to other cheaper guys, risking losing it all, or do as you plan and get in there to secure your future.
