Bet the construction workers want one of these on-site

Saw one of these trailers going down the road a few weeks ago, and finally thought to look it up. Apparently Blacktie Services is an upscale version of your standard porta-commode. It's a bit trippy to see a rather large trailer heading down the road with several doors on it (one labeled "Men", the other "Women"). (Update: The trailer I saw was apparently the Top Hat 240).
