I do, sometimes Im feeling more generous than other times, its human nature. Sometimes I make a mistake, sometimes I dont.
People pay what theye prepared to pay.
I just priced up a gutter clean today, its £85.00, I was surprised at how eager she responded, all things considered (shes an O.A.P, I generally get negative responses for jobs I price for elderly people, they have to watch the pennies more), she in hindsight would have paid more, it seems, however if it had been a professional couple living there the price would have been more, but I can live with £85.00; and so it seems can the customer.
