I am working for an Engg college. Once for the computer lab, one of my student came with half uniform (only the uniform shirt and the pant was a jeans). My lab staff was so angry and scolded him and wrote in the attendance against his name as "present, without pant"
My chemistry attender don't know English. In the instruction class, he told the students to mix the chemicals slowly, otherwise it may lead to an accident, as "Don't pour it, poooooooooooouuuuuuuurrrrrrr it"
