If people were a bit more considerate of their fellow travellers and workers, then they wouldn't be travelling or working when sick!
Ah, the "me" generation... Stuff everyone else, I'm the only one that matters and if I've got the flu (pig, bird, bat, horse or whatever) then it doesn't matter if everyone else gets it too!!! Show a bit of concern for your fellow man (that's "man" gender non specific, before the "women in comfortable shoes" out there attack me).
And before the horses all bolt from the stables, yes, I understand that some people may have the virus (or any contagious illness) and may not yet be displaying symptoms... Case forgiven! But for the rest of the selfish bas#@&$... I hope your noses fall off!!!
"Live long and prosper..."
