If its one customer who's house is say £80 a clean and they ask to skip winter and then I can understand some being upset.
Or if it was 15 - 30 odd customers all cancelling till spring, again Incould understand some not being happy.
But one or two customers............get a grip folks. Like someone said to me a while ago, how many new customers have you gained leading upto winter?? So in actual fact to where you were a year ago from now,,,,,,your actually doing well so its no real true loss. Stop taking it so personnally people as if you have some claim of righy to how they spend their income and to how they choose to employ
