By the way, elfie wrote under another post:
“I haven't been to China for 18 years and have no plan to go over there.
Why? I don't have a life there, zero, zilch. Let's forget about it entirely.
I can't tell you how much I loathe it, everything and all things there, including the food and the surroundings.
Do I want to sit on a little bench munching stinky tofu and premature birds in egg shells? Not me.
Just thinking about it makes me fringe.”
What does it mean by “Just thinking about it makes me fringe”?
Just thinking about eating stinky tofu makes you want to attach some fringe to a rug?
”一想起吃臭豆腐就想给地毯加几个穗子”？
It does not make much sense.
Just curious.

This is a universal quantification in propositional logic.
To prove that a universal quantification is false, it only needs a single counter example.
Since Barrow Salon is a counter example, the above statement is false.
This is basic propositional logic.
Another example may make it more clear:
Someone may make a universal quantification: “Birds never fly.”
To prove that statement false, you only need to give a single counter example, a bird that flies, such as an eagle.
If that person continues to argue: “What about chicken? Chickens don’t fly. Therefore, I can claim that birds never fly.”
Then that person needs to learn a little about propositional logic.
When you say “never”, that means “not a single one”.

Yep, San Francisco salon, what about Great Clips? I'm talking about barbershops in the South, not luxury Salon. You know you can't afford that. Unless you're the 1% most wealthy, you'd think twice where to spend the money on a haircut.

Even now it's $15/person.
A few years ago it was $10.
No one would want to go to the barbershop anymore if it costs $100!”
The above statement is not true.
Example: Barrow Salon, San Francisco. Haircuts: $175.
