You say he did not give a demo lesson implying the other teachers who joined EF Dalian before him also did not give demo lessons. The school must have seen, long ago, no benefits in demo lessons nor the necessity for them until some smart alec said otherwise and influenced the management … no, you make yourself look like a fool trying to justify giving demo lessons. So many posters have spoken against it. Sorry, we really don’t need you to tell us . . . (sigh)
