Perhaps, but phobias aren't about being rational.Dags90 said:Aerosols won't give a shit about a flimsy stall door, and the aerosol produced can last for up to two hours, and bacteria and virus aren't completely eliminated by flushing.[footnote]http://www.ncbi.nlm.nih.gov/pubmed/16033465[/footnote] So scratch having a particulate mask on when someone flushes, just don't go inside at all.Jonluw said:Don't people normally flush public toilets with the door to the stall closed?
Or are you thinking of urinals?
In which case I'm guessing they'd just avoid urinals altogether.
So long as they don't feel they come into direct contact with the 'spray' itself, I'd guess they'd be fine.
I don't know anyone with that kind of phobia though, so who knows?
