Oh, here is a fun idea for you, since you live in the Bay Area...go down to the disgusting Bart Station that takes you to the airport and stand there for 5 minutes at a ticket machine and see how many scumbag, animals try to scam you, touch you physically, try to intimidate you or just grab your money. Now, make sure and be very nice while they are abusing you....don't get all p o’d if they call you all kinds of names if you don't want to hand that $20 over to them for the kind “help”. And if somebody clubs you over the head and steals your wallet, do make sure not to call an evil cop.
