Another completely true one. Honest.
Before Wife and I bought our business, I worked for a huge Firm that had quite a defined level of staff categories. I had to work for any one of several bosses, most of whom were less than half my age but they all had a University degree. I admit I went to university once but that was only to deliver a load from my Taxitruck!
Anyway, one day my boss on one job was nicknamed "The Terminator" because he got so many people sacked. He was quite a nasty piece of work, he phoned me at the premises of a client. He gave me quite a hard time over the phone and in the end, I said, "Well, you told me to come here today, Andrew"
When I hung up the phone, I saw all the staff of the client standing around and obviously listening to my side of the conversation and they knew who I was talking to.
I smiled at them and said "It is difficult to Soar with the Eagles when you are held down by a Turkey."
They all laughed and we all went back to work. The Terminator was never able to get me sacked, although he tried several times. The big boss was a car enthusiast and let me drive his veteran cars.
I have my shoulder to the wheel,
my nose to the grindstone,
I've put my best foot forward,
I've put my back into it,
I'm gritting my teeth,
Now I find I can't do any work in this position!
