BTW, you don't "employ" a self-employed tradesperson - you can only engage them, or hire their services. Since you're self-employed I'm surprised you didn't know that.
So nice to meet the resident DIYnot pedant so soon after joining
How does just one [hypothetical] RGI's feelings tell you anything much about the feelings, or behaviour, of all the real people in the that trade/industry?
Since you're being so pedantic, I'm surprised you didn't know that the above statement is, grammatically, incorrect. You also missed a comma between "self-employed" and "I'm".
Having now spent some time looking around the forums, I am unable to find any posts which you haven't stamped on with your size tens. If you have a spare few minutes when you're not sticking your rather large oars in, maybe we could engage in some grammatical jousting, pedantry pugilism or perhaps even a spelling test. A true David and Goliath contest between the undefeated champion pedant and the apprentice devils-advocate pretender. We can make it multiple-choice if you so desire.
