Pro Plumbers

In the early evening of June 17, 1971, Henry Kissinger held forth in the Oval Office, telling his President, and John Ehrlichman and Bob Haldeman, all about Daniel Ellsberg. Kissinger's comments were recorded, of course, on the hidden White House taping system, and four years later, a portion of that tape was listened to by the Watergate Special Prosecution Force, which was then investigating the internal White House police unit known as the Plumbers.
My plumbing experience was  to have the plumbing  disconnected under the sink so the counter top and new sink could be installed.  I thought the service  of $115 was high, but usually if there is an additional fees, it is usually rolled into the cost of repairs or labor.  This company also charged 3.75 % for putting it on a credit card, which was not mentioned until I received the invoice in the mail after paying on the phone.
The movement of liquids and gases through pipes is critical to modern life. In homes, water is needed for both drinking and sanitation. In factories, chemicals are moved to aid in product manufacturing. In power plants, steam is moved to drive turbines that generate electricity. Plumbers, pipefitters, and steamfitters install and repair these pipe systems.

I think it is rather rude and a bit dishonest for people to not divulge their total fees upfront, an of course we should know to ask. But the normal person wouldn't know the questions to ask until they are burnt once like this, and then there still could be costs for walking up stairs or charge another service call if they need to go somewhere to use the bathroom and come back. THAT ISN'T A QUESTION I WOULD THINK TO ASK.
The word "plumber" dates from the Roman Empire.[3] The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes[4] and some were also covered with lead, lead was also used for piping and for making baths.[5] In medieval times anyone who worked with lead was referred to as a plumber as can be seen from an extract of workmen fixing a roof in Westminster Palace and were referred to as plumbers "To Gilbert de Westminster, plumber, working about the roof of the pantry of the little hall, covering it with lead, and about various defects in the roof of the little hall".[6] Thus a person with expertise in working with lead was first known as a Plumbarius which was later shortened to plumber.
