Sometimes smoking while droppin' a klinker is the only way you can stand to be inside one of those things to do your business!! We had two on the last job that did not get emptied for almost 4 weeks!! There were easily 20 guys on that job daily. The first week when they were scheduled to clean it was 20 degrees outside so the guy wrote frozen. Did not come back til the following week, wrote frozen again!! This continued until I finally got fed up and was having to leave the job to go find a place to do my business, yeah, they could fire me, oh well. The stuff was to the top of the seat!!!! The super on the job knew about it and did nothing, he was a "richard" for sure. I called the porta john folks and told them, "I'm just a concerned worker on this job and these porta johns are unacceptable" gave them the contractors name and location and also said they could have exchanged them if they were not able to be properly cleaned. They were out the next day with two new porta johns. When the guy showed up we hung our heads out the 2 floor window and started clapping and yelling, "Yay!!". The guy just laughed and waved. Suppose the super was probably ticked and was wondering who in the he__ called. Oh well, the guys on the job were happy once again, kinda became a small celebrity, "you called??" Yep, I did it.
