I’m just addressing the fact that Reddit isn’t always correct and we should want more credible sources than random people submitting things online with no vetting. That’s where they aren’t entirely wrong. I’m not saying they’re right and their memory is a reason to believe this is incorrect, but they’re just some person online just like the Reddit user.

They’re not entirely wrong though. Remember how Reddit “caught” the Boston marathon bomber?

It can also be used for people with disabilities. And while it is more expensive it can be much quicker and lead to shorter line times.
