I really wish they would just stick Octopus on, would really save a lot of time for us and drivers. Also there are occasional accidents where someone ploughs into the back of a bike that's stopped to pay. What I do is stick my Kriega Kube Pocket (http://www.kriega.com/kube-pocket/) to the middle of the bars and have cash in there. Still, the other day I opened the zip and it almost tore my $100 in half, and the attendant wouldn't accept it for around 2 minutes whilst I explained I had no other money on me and everyone had to wait behind until he finally took it. Other times I've dropped coins all over the floor because my gloves picked them up with the cash.
