I went to quote on one a while back and quoted £17 she said £15 i said fair enough, they were dirty and the frames were very green but i thought it will probably be a regular so i can afford to take alittle longer the first time, then she said if i give you £30 will you give the frames a good clean,then she said no that a horrible job ill give you £40 i just agreed and she payed me up front.But that doesn't happen very often but it's nice when it does.
But today i quoted £20 for a house and it should have been £25, but she only gave me the £20 she knew it took a long time and it was a good deal, but i cant complain as i should have quoted more, but we learn from our mistakes.
