1. Purchase a Starbucks card, load $5, and register it online.
2. Save your last "paid for" cup, or pick one out of the trash. Your discretion.
3. Refills are forever free after that. $0.52 cent charge becomes $0.00 when you present your registered Starbucks card to the cashier.
4. Lifespan of reused cup is 4-5 refills. When cup deteriorates and develops heavy leak, request new cup, pour contents of leaking cup into new cup, and begin cycle at step #2.

Discuss pros and cons to stay awake during long flights.

But hey, I'm living in a van and have time to kill on APC attempting to encourage total strangers to crack a smile....
