... and that's why I wrote that.
I can vouch for the same thing, although not 55 years worth, lol!
The point is, we plumbers are a skilled craft. We have invested time to become what we are. We should not be ashamed of what we are, but proud.
When I read about all the detrimental experiences that people have had with plumbers, I wonder how many of them were actually licensed.
For the customer, the license is your proof that you have a qualified person working for you. If you have any qualms, simply call the licensing board listed on the license.
If you didn't ask to SEE a license, shame on you...
