Last time I mentioned those time-wasters who call or email on the pretext of getting a quote, or sometimes even without the pretext, just to get free information. It is so annoying.
However, we can understand that not everyone wants to pay. Many do want a free ride. The downside for them is that even if they do get free information from one of us in an unguarded moment, it is probably of little value.
Think about it. No telephone call or brief interaction will entail a proper exchange of information for the free provider to give any useful advice. Vital facts will get left out, context will be missed and comments will be misunderstood.
If your free-loader has not paid for something, he has no comeback if the advice he got was wrong, whether based on a correct understanding or a wrong one. He has no one to turn to if there is a hitch, even if the free advice is correct. He is floundering in the darkness rather than having paid for advice, help and support which should be of real value. There is no friendly ear to listen to the problems and no helping hand to steady the ship.
Free advice is useless unless it is from a friend. Then it is paid for in another way and given by someone who cares and is committed. You give benefit through your friendship, and you get pleasure from giving too.
If you need free advice from a stranger, make sure you pay for it and have a proper agreement of the terms. Then you know you have something of value.
