I know an Olympic medal triathlete who complains not about the training, the odd hours, the inhospitable facilities, etc, but about the random pee tests. The testers come any day, any time, although she thinks they have a preference to come Saturday nights right after she has just had a potty break. Then they get to sit around for an hour in her apartment while she drinks water until they can observe her fill a specimen bottle.
Sidewalks and curbs on Preston Street also undergo specimen tests. Here are three containers of concrete taken from sidewalk pours on Preston at the corner of Elm Street. They are used to prove the correct type of concrete was used, and can trace any problems with the finished sidewalk back to the original concrete mix vs subsequent damage from abuse or other conditions after the sidewalk was laid.
