How many ways can they rob us?

I just found another one!

There were periods in my life when I didn't follow the rule that breakfast was the most important meal of the day and that I had it at different times of the day.
Several times, due to the large crowd, I skipped breakfast and put the first food in my stomach after noon.
When it affected my health, I decided to change my habit.
Since more than ten years ago, every morning (when it's my working day) right after morning exercise and shower, around 6am, I have breakfast.

It doesn't have to be a strong and high-calorie breakfast, sometimes I just eat toast and two slices of thinly sliced ​​ham and some butter or cheese...

And every time, I eat a glass of sour milk.
I used to drink yogurt, however, after consultation with a nutritionist, and my comment that it doesn't matter to me whether I drink yogurt or eat sour milk, the recommendation was: Sour milk.
I accepted.
Since then, I always have a few glasses of sour milk in my fridge.

After breakfast in the early morning, with a glass of sour milk, I can easily wait for lunch during the day, without being hungry or feeling nauseous....

Sour milk (as well as yogurt) is packed in plastic cups here, and it has always been 180 ml.

That's why this morning when I removed the foil from the glass, I immediately checked the amount indicated on the packaging.
Yes, 180ml is still written on the glass.
180 ml sour milk.

But under the foil, certainly something less than that.
The reason?

The sometimes solid matter of sour milk, which is most often eaten with a spoon (tablespoon or small coffee spoon), generally fills the glass evenly to the edge of the glass.
There was never any liquid in that glass.
That is, never until now.

I opened one glass, the second, the third...
The same in each.
When pouring sour milk, less was poured into the glasses.

It's not much less, but the surface is no longer flat.

The manufacturer gently stole one teaspoon of sour milk from each glass that he sells to his customers, and filled the volume with some liquid that should be spilled when opening.

And so, if I calculate that I eat ten glasses of sour milk in the course of two weeks, one glass was stolen from me.

Sour milk is not expensive, but if you already sell less sour milk in the same packaging, at least state on the packaging that the volume of the product is smaller.

As the confectionary industry did, they kept the prices, and in chocolate packages, instead of 100 grams, they now pack 80 grams or instead of 300 grams, they pack 275 grams.
But that's what they indicate on the packaging.

And these thieves leave the same volume written on the packaging, leave the same price of the product, and instead of filling the product with product, they fill it with water.

Have you also been in a situation where you pay the same for less or have you discovered a similar fraud with the amount of products in your everyday life?

And yes, do you eat breakfast this early, like me?
