Here's a nice story about a generous piano technician (from The Week).

Yep, I believe it is the same @navindra .
I wonder how that piano is holding up.
Also, it just amazes me how casual people can be about putting drinks on top of pianos.
I have a little “pop up” sign thingy for my piano for when I have parties at my house. It says something like “you are welcome to play the piano, but please, don’t put anything on it. Especially no drinks!”
The other thing I got into the habit of doing is to always open the lid. Usually, I keep the lid and the fallboard closed when I’m not playing my piano. But when I have parties, I actually open both and set up the music stand. I put the little pop-up sign on the side of music desk, the flat part. With the lid up, that’s the only spot where you could put a drink. And the way the room is, if you walked toward the piano, you’d see that sign before walking around to face the keyboard, so people see the sign before they would get into position where they might put a drink on the keyboard as well. I think it works well that way.
But maybe that’s not practical for O’Hare Airport. :/
ShiroKuro I suspect that rather than being an issue of it being at an airport, I think the issue is that it seems to be the property of a bar… and they’re using at as advertising for liquor brands, so it probably cuts against their business in some way to restrict what people do with their drinks.
It's refreshing to see a young person with such a great work ethic, doing something to benefit the community. 
To be honest, a lot of people show little respect for any public space area, including anything in that space - they just use it to suit them and leave their mess for others to clean up. We need more people like this young man.

Speaking for my wife and myself, neither of us would like people handling drinks, especially red wine (no food, either), in our living room, where the piano is located. Anybody that would be our guest would be understanding in this respect. A piano is not a table nor a bar!
Yesterday evening I made a cup of tea and was going to sit at my piano and do some hands separate work (tricky right-hand part on one piece, and a tricky left-hand part in another piece).
Then I thought about this thread and that YouTube video and decided to just sip my tea away from the instrument.

Once I was on vacation and came across a piano at the airport terminal in my city. I remembered a young student sat down and played an arrangement of the Mozart Symphony #40 in Gm mvt 1 theme... probably from a book for easy piano. Travelled out of the same terminal a few times after but no piano. Wonder if the airport admin people have the incentive to keep a piano at the terminal to let travellers entertain themselves?
Anyway, nice to know some airports have public pianos. The young man who fixed the piano didn't say what brand it is and the approx. age of the instrument. Lucky the piano mentioned has no broken keys. About 2 months ago came across an old piano at a second-hand store. It's a local brand that existed at least 50 years ago but no longer in the market. The piano does have some chipped keys and they are definitely out of tune. Some are not noticeable but others are at least half a pitch flat. Tuning is not the only issue. When keys are chipped, there is safety concern in case somebody cut their fingers while playing.
I would play different pianos in a store occasionally but haven't played on a public piano for a few years. There used to be an old "Made in Canada" Heintzman upright at the entrance of a community center. I played an arrangement of Shostakovich Waltz #2. A man walked by with his young daughter thought I was a piano teacher at the center.

The article indicates that it was a "Kimball baby grand piano".
