One day, I arrived at the clients to find I had forgotten to replenish my glass slides that I use for microscopic examination of wet mounts. Panic! What to do? Battle through traffic to return to base? Find a local veterinary clinic to supply?
I put on my “Bear Grylls” / improvisation thinking cap on, I asked the client, would you happen to have take-away containers?
Using my trusty scissors, I fashioned a slide and coverslip. Wallah!
