Artistic Temperment on the Street (On Polk)

I love fried chicken. If I had to pick a death bed meal fried chicken would definitely be part of it. Sundays at Street on Polk is fried chicken night and they serve as superb a piece as I've had outside of the South. Along with the chicken, the plate includes mashed potato with gravy, sour cream cornbread and a wonderful but disappointingly small serving of corn off the cob. The ratios weren't quite right so I asked for more corn. I was informed that I couldn't have more. So I assumed that the bartender misunderstood my request. So I made her a proposition I was sure they couldn't turn down. I was going to pay for another entire entree but all I wanted was the corn. Still no joy. Apparently, the servings of corn are so precisely measured out that they could not spare another serving EVEN IF I PAID FOR THE ENTIRE ENTREE! Okay, I understand that chefs can be picky about their creations. And I would understand this if I was dining at Scott Howard. But fried chicken? Are you kidding. Bad service and idiotic business practices. I'm surprised that this restaurant has been around as long as it has. Jim, is chowhound useful for something like this?
