I have worked for the same commercial cleaning company for the past 10 years.
While I would say most of the things I see are fairly normal, there are some really weird and gross people out there.
A great example is my neighbor Adam. Adam used to get cleaning service from another carpet cleaning business all of the time. At first I thought this was a great idea, it’s great to see people taking interest in their flooring, and making them look cleaner and better. But one time when Adam’s usual business cleaning service was shut down for maintenance, he came to my floor cleaning business. I was sent out to his house, which wasn’t any issue since he lived right next to me and I have been to his house before. All of the other times I have been to his house, it looked normal, but I am guessing that’s because he had commercial carpet cleaning service beforehand. When I walked into his house and saw his carpet I was appalled. The best way I could describe how it looked, is that it looked like he released a thousand wild animals in his home without any way out. Stuff was on the floor and old food was still left out. The worst was the carpet though. The carpet, which was originally a tan colour, was now a deep shade of brown. I honestly was scared to guess what that might be from. When I got to cleaning it, tears formed in my eyes from the foul smell that was unleashed from those stains. It was horrible, and I couldn’t wait to get out of there. On the bright side, his carpet was back to mostly normal looking.
