Some windys are still living the dark ages. By that, I mean those who think they have a God-given right to monopolize an area.
It is usually someone who does a lousy job, has a big mouth and little other bits, and nothing to back it up other than threats. These creatures often intimidate their (unhappy) customers into putting up with them as 'they are the local window cleaner'.
Anyway, back to the 21st century, we live in a land where there is free enterprise.
Note to the above mentioned Neanderthals: This means that others have the right to look for work and pick up customers in the same vicinity that you operate, but who don't want you.
Best wishes to those who are starting up.
