I was a construction inspector for a large corporation a few years ago. A contractor (former) told me, "It's my job to cheat and your job to catch me." I pulled out my Sony Mavica digital camera and documented a day's infractions on a box of floppies and emailed them to our engineers and the legal department. The next afternoon a warning was issued and the following day he was removed from the job. He laughed at my diligence and our specifications but the pictures wiped the smile away.
The macro lens I had allowed me to take pictures of the tiniest details. I could get 12 to 14 pictures on a 1.4 meg floppy. The times are-a changin'...
Our water comes from Lake Erie via the Cleveland Water Department. Problems such as this is the reason we still have a cistern. I have always enjoyed the fresh taste of Lake Erie water, but I don't trust its delivery system.
THANK YOU! Since I've retired I help with all the housekeeping. I have never been able to get fitted sheets even halfway uniform. Great link, thanks again.

I showed the video to my bride and she laughed at me, "I've shown you how to do that twice, you dim-witted old has-been." That's her pet name for me. Maybe it's time I start listening to her, but after 47 years years of marital bliss why change? ;-)
