First and foremost you need to inform customers of the cost of parking the arena b/c if I knew it was $15 I never would've bought the groupon. Second of all they refused to give me my free hot dog and soda because I didn't print the actual groupon out which I never do. The instructions said show them voucher, I showed itto them on my phone and they said they needed it printed. This was the worst groupon experience/groupon waste of my hard earned money ever. Get it together.
