Rarely eat at McDonald's, and usually learn or see something interesting. This time I saw a table with two kids (guessing ages 6 and 8) on their own for a long time. Then their mom (I guess) sat with them for a bit, a McDonald's employee.
When chatting with a friend that says wakes up at 4am and goes for walks (I suspect anxiety), learned that days such as January 1st are extra trouble because everything is closed, even McDonald's!
