This week I was flying out of Pensacola for the first time. I always take my waterbottle out and place it in a bin to avoid issues on the other side of the xray (20 seconds to take it out saves the few times I have to wait 5 minutes for a bag check). There was a TSO manning the entry to the xray arranging everyone’s stuff. He took out my water bottle, pointed to it, and said Gate 7. At first it took me a second to understand since I was mentally prepared for a “liquids are banned” or something like that.
Instead he was telling me where the one very hidden water fountain is in the airport. I might not have found it otherwise and I would have just used a sink which works just as well with my filtering bottle.
