I had to use that shit all the time when I worked at McDonalds. Fucking retard coworkers would pour grease down the sink. I'm not joking. Snake, then flush down a ton of soapy water.
Maybe the deal with those low flow toilets is so it uses less water when flushing after just pissing. When you piss, flush once. When you dump, flush after you dump. Then flash after you wipe. Then flush after you wipe every time after that.
