There was a dude on the train the other day standing near the door. He had a satchel bag in front of his body when some sort of amber liquid started to pool around the floor.

I could’ve said something but we just had a lunatic on and I would’ve had to shout YOUR LEAKING because he had ear buds in and I didn’t want to embarrass him because I didn’t know what kinda system he had down there. Pointing wasn’t an option because he was staring at the roof.

Then he swapped doors, looked down, felt around in his bag and pulled an empty keep cup out. I was relieved. He was not. By this time that trail has made its way down the carriage.

So guys if there is some wisdom I could pass on to you is this - don’t put all your faith in a keep cup in your bag. They will eventually let you down.
