I agree about 'metal tube with all the coughers and sniffers'.
We intended to go 'up the city' on Saturday (not that there Lunnon, just Naaaarwich) on the Park and Ride bus. But I'm not keen as people do indeed cough and sniff with no hanky, and the windows are always shut. Box of germs. I'm furious when people just sneeze loudly without even covering their mouths/noses. And cough all over everyone too.
I wonder if one can buy a Hazmat suit on Amazon? Perhaps my husband could get a fancy one with Man U or Arsenal logo printed all over it?
