How to fool Civil Guards by an amateur Drug Trafficker:
1. Convince a near century-old lady to join you on a trip to the land of España
2. Discretely strap the packets of coke to her frail legs and torso
3. Insist that your 'grandmother' be given a wheelchair at the airport
4. Smile as you bypass security checks
Arriba, Señora, arriba!
Unfortunately, you kind of blew your cover with Customs control when you ran away without Nana. Sorry :/
