Wow, isadora .. Why am I not in the right places at the right times ...
Well, I got a couple of those. Whle travelling from LA to houston on Amtrak , the train ran out of drinking water and the cafe car was closed and the guy wouldnt open it. So when we stopped in san antonio, I ran to the vending machine and bought a bottle of lemonade (water was out there too) and ran back (and needed water thrice as bad). When I reached the train, a guy who sat somewhere around was trying to quiet his very young kid who was crying because he was thirsty. So I offered him my bottle of lemonade and ran back to the vending machine pretty decent jog away from the train, train was alredy anouncing "all aboard". The moment I reach there, I realize I was out of cash ... I had more cash in my bag with the bag in the train !! all the people were back on the train, already!
So I ran out of the station at 3:00 in the night and tried to panhandle a buck and a half from people around, after weird looks from about 4 to 5 people, a very pretty looking girl gave me the money .. which I fed to the damned machine and got another lemonade
phew.. that was long, I am thirsty again
