I went to a Cubs game for my birthday last Sunday and have this to say about the new rules. You have to pay attention much more now, things move fast! Also there is no cash at the fields now, all on cards and the vendors come by much less than the used to. I stopped at my buddy's bar across the street before and afterwards and he said that the vendors are not happy as they have less time to sell beer and hot dogs which means less money for them, and all the fru-fru foods available at the concourse have cut into their profits too. I did learn you can still tip them with cash though and they will come back to you more often if you do that...
