ICE at Santa Monica151

On 1/32/10 at around 10pm, I went Santa Monica for a casual date and found this ice rink place and thought that I would have a nice and fun time there with my girlfriend. The admission (including rental) was only $10 and the place looked really cool. But rude and unfriendly service happened when they transacted my credit card and they gave a receipt for me to sign so I did. Then a "rude" lady told me that it has rejected(?) the transaction. But what did I just signed??? So I gave her my other credit card and at the same time I asked her if I can keep the other receipt that has my sign on it. But she refused to give that over to me, which I or anybody couldn't understand. That's how the argument broke out and then she got very rude and told me that she was not going to argue about this(???). Was I asking a wrong question??? I think I was only asking a VALID question. Now I just have to watch out for my next credit card bill to see if they have charged me TWICE. Two thumbs WAY DOWN.
