LMAO at the Commando comment, if you've not done commando at work you're not doing it right!
I agree with the wash basin comment, you feel good after a cowboy splash. I would ask the cleaner to conveniently leave the mop in the toilet area just in case you splash alot.
The one place I worked at was a 16km to and 18 - 22 km commute home depending on how I rode home. The toilets had to way to lock so I took a door wedge with me to work and locked it from the inside, those ******* were consfused for months as to why at a certain time of the morning it was locked!
I miss commuting, would love to do it again.
