That's not nice Michael and I feel for you. Tell her to get a quote off Ben's Gutters. That'll shut her flute up when she finds out what they charge. You've done her a favour and she should respect that, ill or not.
Aye, sometimes I feel like a social worker, she realised I had an answer for everything she hit me with but couldn't back down. Must have took her 5mins just to get to the door, poor soul, her husband just stood there. Plus side, picked up another customer round the corner from them and now have half the small estate where I live.
