Do you really think i'm gonna take a sealed box without checking its contents first ? 
I never buy anything locally without examining it first and making sure it's fully working and in good condition so no pixies for me, thanks...

Sure, you might, but a lot of people are more naive, just take the thing and walk off.
But testing the thing is dangerous as well. You are meeting a stranger, and have to go together to his gaff or your gaff to test the thing, its not like you can test it in the park
Sure you can. Raspberry Pi and USB battery pack. Never leave home without 'em.
