I'm thinking about What is a "real-life" example in the United States of a price-searcher (business firm) that currently practices what the textbook defines as "price discrimination" (and is also referred to as "differential pricing") at one particular (the same) location?

my friends said

I think goods and services manufacturers regularly use price discrimination techniques to ensure that the segment and all its customers are properly served. This is usually done to ensure that those who can pay higher prices for the same basic service receive additional advertising on services that others do not receive. The basic offer or purpose of a service or well-being is still the same and includes people who may not have enough money to pay business owners, but still have a significant share of the total demand for good or service. This type of pricing strategy is used to increase profit margins and is used in markets where competition is relatively high.

Important examples of this are the cinema industry, where we charge different prices for the same film, people who prefer to sit in seats that may differ in quality or position Currently, movie theater want to take advantage of the maximum income possible from all sections of society that may have different priorities and budgets so that they can pay the ticket prices for these services. Consequently, the business owners subdivide into various screening methods such as general screening, night screen high-quality screen, and 4D screen. They allow owners to maximize their profits. However, this is just one example, and prices will vary depending on the situation, the relative cost due to competition, and operating costs.

in this post, I want to know this statement is good or not. also, why.

please include that your own understanding of the practice of price discrimination (differential pricing) in the product market.
