curious, why do people like to use their laptops or do their school work at a coffee shop? isn't that more distracting?

i was at a coffee place in los angeles the other day and i saw a big table filled with people sitting in all sides of the table with their laptops out and with their earbuds on. it looked like they were in a classroom.

there is always constant distraction, customers coming in, and people talking which makes me wonder how these people do not get distracted easily?

If i needed to get work done and my home was not an option, i would just go to the library.
