I agree, tips should be something earned and I think it's awesome you gave double to those that deserved it. I actually tipped two different coffee shop employees about a week ago just for getting coffee and I don't think either even thanked me. No more!
Here, we say "thank you" when leaving a bus. I have seen people try to tip the driver.
I learned that you ALWAYS tip big and up front with a parking valet, NEVER tip at the stands at sporting events, and always round up for a cabbie to at least 20% or so because I like cabbies and they treat me well. (They see my cane and immediately get out to help me in even though I don't need it)
But, as you raise, we have certain societal habits that have grown way beyond what was originally intended. This "pooling" or, call it what it is "wage top up" is the result of good intentions becoming political movements which then **** everything up.
This is the real "government overreach", which I have fought all my life, from the first park board meeting I covered as a cub reporter through to the United States Senate, the "Phineas rule" comes into effect. "The more people involved in an idea the more likelihood the reason for the idea will become irrelevant" Example.
Politicians in Canada like everywhere else like to be on the "right side of an issue", and so anything dealing with say, smoking is going to get you some attention. Councilman "A" says there's a problem at the beaches and the parks with cigarette butts all over the place. And he is right in some cases. The "idea" is to make more "fireproof" ash trays for people gets presented by councilman "M".
"Now wait just a minute!" Council woman "B" says, that's just going to encourage people to smoke! Think of the children"
Now is where councilman "Z", who is eyeing the mayor's job, gets the sure fire way of getting a headline. "Let's ban smoking in parks and at beaches."
Suddenly the chamber is quiet while people try to find a way under that limbo bar without seeming to be "Pro-smoker", God forbid.
Now, councilman "P", who actually is quite bright points out that such a ban would need enforcement, so who's gonna write the tickets.
The matter will be shelved with this new development, as people line up on one or the other side as the "idea" fades from coverage...
Until an election surfaces and councilman "Z" unleashes his "3 pillars of healthy parks. A fancy way of saying 1 Parks are good. 2- We all like parks and 3 Let's ban smoking in parks.
Now councilman "c" says '**** it" and goes fishing with Phineas and the council is elected on a straight platform of banning smoking.
Later that spring, the newest kid on council says "you know, there's all kids of cigarette butts all over the parks, trails and beaches. We need to do something."
Which is where Pogo enters and says "I have met the enemy and he is us!"
