A couple reasons why I hate doing port work after others

I am Done working on other people's stuff!!

If they bring it to my shop, I will fix it for free if I can do
it in less than an hour for no charge given they leave
it for a few days until I can find the time.

Beyond that, I will give them my opinion, but I will not
put my hands on it! If they argue with me about my
advise (common) that will be the last time they receive
any from me.

At 75 year old, I have come to the realization that I have more
money than I have time at this point. I have lost patience with
time wasters and folks that grind me to death on the price of something!
I got out of the wrench business years ago mainly due to customers. Near the end of my 20 year career ( I was out by my early 40s) I used to say "There isnt anything that constitutes an an emergency unless my car doesnt start when I go to leave here at 5 o clock..." :) Oh yeah they loved tryin to get you to stay late for "emergencies"
