Is it normal for indian people to keep cups next to the toilet?
So I work at an office which is mainly populated with people who come from India. Like fresh off the boat, no English, Indians. In the bathroom, there is always a water bottle or cup sitting right next to the toilet. It has water in it, and it will change, sometimes a water bottle, sometimes a cup. Which means it's getting used and moved. Until recently I could only imagine what it was being used for specifically. Until I went tk the bathroom, and saw on the cup that was there a HUGE brown streak, about as thick as my thumb, right on the side of the glass!!
I guess my question is, is this normal Indian behaviour? Only the white people in the office are put off by said cup, non of the Indian guys mention it or even seem to care. can anyone shed some light on this subject? Is it beig used the way I think it is?
