Cheap Parking or Getting Towed?

I got cheap parking for the St. Louis Blues playoff hockey game online. SpotHero.com hooked me up with a spot less than a third of a mile from the Enterprise Center for $2. Too good to be true. And it was. The parking attendant wanted cash. Said they didn’t sell spots online. He wanted my phone to call someone. Just hand it here. Ugh.... no. He yelled. He threatened to tow me. I parked. And for only $2 online! I wonder if he was even a parking attendant or just a guy taking people’s cash?
