Anti-Social Toilet Manners - Ego or Cultural?

The two cases are probably unrelated but the journalist has put a negative spin to continue the derogation of immigrants.

Now, I am afraid that feminists might protest if signs have been installed in male or unisex toilets where seats are frequently wet by inaccurate aiming at the target. This is a serious issue which has been the cause of many family quarrels between husbands and wives as well as siblings. But in public places, no one knows who did it!   Ask anyone if this is unique to non-Australian culture, I fear not. 

Quote : 


A UNIVERSITY is teaching migrant students how to use a toilet correctly after complaints from cleaners that they were leaving them in an unhygienic state.


The signs were installed 15 months ago after complaints from a company contracted to clean campus toilets.

Why only confine to a certain university? These signs  and more should be displayed in all toilet cubicles all over the world to educate users and make the jobs of cleaners easier, or even save payroll expenses by hiring fewer cleaners!
