Although Wendy's and burger king are pretty good, I'd rather swim in a McDonald's dumpster. Usually they all smell pretty bad but the interior of McDonald's masks the smell of the dumpster. My first reason would be that the McDonald's dumpsters tent to be more tidy and well kept. All the trash is within the bags and the viscous juices tend to fester more towards the bottom. My 2nd reason would be that McDonald's never really goes bad
