Yoh I'm tired

The branch in Hatfield, Pretoria (Illinois Spur) is extremely slow. Waiters are indifferent on most days and are slow to complete orders that don't even need the kitchen to finish making it. The other day I asked for ice because they served me a warm drink. I got it over 20 minutes later. By then I was done eating. What annoys me is that this issue is persistent, even on days when the branch isn't busy. The waiters just stand around then we get weird looks when we don't tip
