What does the highlighted text on the second image mean?

A queue wrapping all around the building

**Costco** is a store. A **line** is a queue of people waiting for something. A **block** is streets intersecting. A **store** (like Costco) is usually built on a street on a block. **There's no way** is en expression meaning it seems really unlikely. A **line around the block** is a queue that feeds outside the building and down the street and around the corner. "There's no way that Costco didn't have a line around the ~~the~~ block." **the the** is a typo. There's only one the. The comment is saying that it seems extremely **unlikely** that there **wasn't** a long queue outside Costco. Or (if you remove the double negative): it's extremely **likely** that there **was** a long queue.

The comment is saying that there's no way the actors from Breaking Bad wasn't a known event. They're saying "no way that Costco didn't have a line around the block" because they don't believe for one second that OP was surprised. The "line around the block" is literally what it says. There's so many people waiting to see/do/buy something, that the queue of people goes out of the shop onto the sidewalk outside and then down the street and around the corner and so on. So "a line" means "a queue (line) [of people waiting]".

A line around the block is an exaggerated way of saying a really long line. In a city, a block is an area of buildings between streets. So the idea is that people are lined up outside a building and the line is so long that it wraps around an entire city block.

No way that Costco didn't have a line around the block. It's not possible that Costco didn't have a line of people long enough to circle the city block. 100% chance that Costco had a long ass line.

A line of people. Because they are so successful, you know? People are "lining up" to buy their products.

In everyday English, saying a store “had a line around the block” means there were so many people waiting in line that it wrapped around the outside of the building (or even onto the next street). So when the comment says, “No way that Costco *didn’t* have a line around the block,” it means the writer is sure the store must have been *extremely* crowded, with a very long line of customers waiting.

a block is typically a city block. The word is used a lot in the US. if you look at a map most of their modern cities are built in a grid/square like pattern for the ease of driving. one of these squares is called a block.

American English for *they didn't have people queuing around the block* (the area of the city/town/village where the branch of Costco (a warehouse-style supermarket chain) was located. Mr. Mayfield is therefore saying that he thinks Costco is very popular
