Re: In the early days...
In the mid 90s, I moved to the Dallas area. Not being certain about flight availability, I booked my flight home for Christmas in early September. The travel agent gave me my tickets, which I put in a drawer in the kitchen.
The day before I was due to fly home, I pulled out the tickets to verify the flights, etc. To my shock, the tickets were entirely black. The drawer was next to the dish washer and the tickets were printed on thermal paper. Oops. Mad rush to the travel agent.
