I was recently contacted by someone asking me to research their recently purchased vintage Browning recurve bow for them. Specifically they wanted to know what year it was made.
Right away I realized what they were asking would take hours of my time and I frankly do not have the time right now to be researching other people's stuff for them. I have my own stuff to do, a toddler, deadlines, work, a wife, a social life, and I don't have time to waste on researching other people's stuff unless I am being paid for it.
PS. There is a wonderful search engine called "Google". I recommend people try using it. Otherwise when you contact someone and you're asking them to research something for you then you should just immediately mention MONEY* and explain that you don't want to waste their time and are happy to reward them for their time.
* Payment in advance. I am not running a charity.
