I recently flew on a Delta A220 and noticed that the bathroom didn’t have a warning about not drinking the water. Does it mean it’s safe to drink or brush your teeth with? This was the only sign above the tap:
Good hand washing takes 20 seconds. Or the time it takes to sing Happy Birthday twice. Use water to rinse your hands before and after 20 seconds of vigorous scrubbing.
