I have seen this , but I see it different suppose they did not check and care at all, if a problem exist at lease they are willing to do something about it. When you have people who will not check and and offend you.
I heard this story
a lady wearing panty hose assumes once she leaves the bathroom All is well until she rolls out the carpet of tissue behind her in a lane full of people with tissue still in her panty hose, Had she been more sufficient in checking , she would have saved herself embarrassment.
I think it is good people check behind them self even breath.
