Hostess gets a 5 star...
Arrived at the airport my battery on my phone was low and I was hungry so I asked the hostess "do you have a table with an electric outlet?" she said absolutely and took me a table. It was hidden and not easy to find but she knew it was right there.
I ate (food is always a 3 at Friday's) and charged my phone.
I have been to 100+ airports and she was the SECOND one to ever know where an outlet was.
