I guess I have a little sympathy for you on that one. I've only played the Plaza twice, but on both occasions I started out on the North machine which raked me through the coals. I switched to the one by the tables and luckily I did so well my average came down to exactly $15 each.
Ever since they refused to let me play for the convention strikes without the special club "pass", I don't play there anymore anyway.
That's another story but after waiting 4 hours trying to get management to let me play, I wasn't in the mood to buy the 2 sets each of the two Hollywood series' from the cage and play the other machine for the $200 one. Boy, they lost alot of business from me on that one.
