to be honest the main reason i never go to the sonic is because i never remember it's there at the same time that i have hunger. also In-N-Out fries definitely suffer at peak times, but theyre still the fast-food king by miles.
The Wendy's in town used to screw up orders about 70% of the time, so I stopped going there for a while. About a year later I went back and it was staffed entirely by Mexicans (or other Latinos I guess), most with practically non-existent English skills. Amazingly, they got the order right. In the 15-20 times I've been back, they haven't screwed things up once. I guess the white high school kids who used to work there just didn't give a shit.
The only reason to eat at McBlasthole is that you enjoy dissentary.
