it happens from time to time …..
I find it best not to have rules set in stone …
if its of benefit for a customer to come back in the spring , ie ,,, I benefit financialy , then why not ?
if it doesn't and its a pain , then its bye bye , or I will increase the price to make it benefit.
I have started to sell to messers before I dump , a as and required service , if they are in the middle of a run of houses.
I charge an inflated price for this , and they have to wait until im in the area . they also have to pay cash for this on the day of the clean .
it rarely happens , but why not turn it to your advantage ?
