Ah when I was trained to look after Students at my University we wre told about this, especially the whole toilet thing. Among others there were cooking smells and waking hours (as Students complain bout that, whereas I find it fascinating). Anyway, the fact this University have to put up signs to stop Asian Students from not standing and squatting on the toilet seats.
It does happen.
Posters have gone up around a university campus instructing students on how to use the toilet properly.
Swansea University says it has produced them to help address cultural differences.
The posters include images showing students what they should and should not do.
