That reminds me of the time I tried to take the bus to the Home Depot next to Richmond Hill Centre / Langstaff Station. Turns out they built a fence all the way around the Home Depot parking lot to prevent people from walking between it and RHC or Langstaff stations (fence outlined in red below):

So I jumped the fence both ways, and on the way back I cut my leg. So I got on the Viva bus with a leg bleeding, and I asked the driver if he had a tissue or something, but he didn't, and I think the best he had on hand was a piece of paper or something. So that's what I used to try to clean up a bit on the ride home.
