About 20 years ago I used to clean for a wealthy women, she owned 2 flats and a her cottage that she lived in and I used to clean all 3 on the same day.
The flats were £40 and cottage was £25 every 8 weeks anyway I digress , one day I had done the 2 flats and then drove about 2 miles to do her cottage in a very posh area of Winchester.
As I was doing the cottage she approached and asked if I could clean out her gutters, I said that I was too busy that day but I could fit it in time in next time I visit in 8 weeks time and the cost would be an extra £80.
She looked at me in total shock and replied ...."£80 ? you're only a window cleaner"
To which I replied ..... what did you say? I'm only a window cleaner ? then you best find another only window cleaner to clean your gutters and your windows including the flats no one talks to me in that in that manner trying to belittle me"
Needless to say I dumped her on the spot, and yes it may have cost me £65 every 2 months but my pride was more important to me.
