I'd like to see a similar test for airports. I always fill up my water bottle in the airport (at one of the water fountains for filling bottles) before boarding.
Don't airlines serve bottled water? Alaska has Boxed Water (same as bottled water).
I also started doing this since it seems to be a nobrainer to bring some empty water container rather than paying outrageous prices on bottled water... But a couple days ago I flew to the US through Heathrow and saw some guy drinking with his mouth from one of those refill stations, and now I'm not sure anymore because I feel like one in n people will touch/contaminate it.
Similarly when I use a public restroom it is shocking to me how many people don't even follow the most basic personal hygiene.
I find it absolutely puzzling that people refill their bottles in those public fountains.
Last time I was in SFO I saw dozens of people doing that in the time it took from deplaning till boarding an Uber and all I could do was scratch my head
