a custy of ours has had a conservatory built. It wont need doing she told me as its self cleaning.
I had a smile and said we'll see.
This is her second conservatory and the other one is always coated in bird nuts as the chap over the road keeps about 5 million racing pigeons.
She looked so proud of the fact that its self cleaning and seemed quite annoyed when I laughed at her.
Time will show
You should not laugh at a customer ever (to her face) inside yes.
I would have said thats great I hope it works, if they start getting to bad please let me know asap to clean them or it will cost more to get them back the way they should be.
they do like nice dont they

give them a compliment helps taking the P out off them does not. if you had of laughed at me I would have laughed back and said your sacked.
Not having a pop at you at all as I know full well where you are coming from I get this all the time, just you may want to look at the laughing at your customers as I feel this is bad for business.
