you poor soul, lass!
in one of my workplaces, we had someone who was infamous for polluting the ladies' loo at around 2PM like clockwork!
you'd scurry to go before she got in there.
honestly, my eyes watered after she'd been in there and i also threw up once. in the sink - didn't make it to the bog.
someone heard me and once i'd cleaned myself up and my boss asked if i were okay and i told him, he loudly bellowed, for all us cubicle prairie dogs to hear, 'someone is polluting the bathroom so bad my team members are puking b/c of it.'
after that she went to another floor to do her biz.
