Ok, I know I am turning into my mother.
Train in this morning, I was standing next to a woman who sniffed all the way in. At one point she opened her handbag and started rifling through it. I thought "ooh, good, it's annoying her too" but nooooo, just got out her phone.
Then the tube to work. Again, very crowded so in everyone is in each other's space. The two people standing against the door next to me were both sniffing. But in time so it was SNIFFF, sniff, SNIFFF, sniff.
AAARRGGHHH!! It makes my stomach churn and waiting for the next sniff is like listening to a dripping tap!
I'm imagining being able to require people without the compulsory tissue to leave the train at the next stop. We could have tissue dispensers on each platform. Maybe even spot checks like the checks to see you have a ticket....
