Im the same i assume the customer will stay with me where they usualy do thank god or id question if im doing my job properly. I try to get everyone 4 weekly with the exception of a few 8weeklys. Maybe its where you charge more first clean they think your taking the mick a bit? Thats why i stopped charging 50% more as found wasnt getting as many customers. Still who cares as long as all are doing well thats what matters.
