We all know that public or office bathroom/toilet are maintained by maintenance/cleaning crew, but that is not to say that we are to be careless in the way we use same.
If you use the bathroom or toilet wash basin, and there is soap residue, be sure to let the tap run for about 5 seconds to allow all soap residue out the wash basin. Don’t forget to wipe your hands and the wash basin area clean, as splash of water rest on that area while you wash your hands to keep the place ready for the next person.
Also there are instances where toilet papers/rolls are left lying on the floor accidently as a result of excessive pull, be sure to take that of the floor too.
Do not purposefully mess up the restroom with the intention that the maintenance crew are paid to do the cleaning. Remember, life is sometimes fair, as it gives to you exactly what you put into it. So, courtesy and manners requires every individual to be responsible when no one is watching; you really do not need surveillance while you use the restroom/bathroom/toilet. Do you?
