When using “excuse me” to ask someone to move out of the way, should “please” be added?
I don’t think it’s needed. I think it is polite in itself. DH thinks it does unless the person is being a nuisance, as otherwise it comes across as an order.
The “acceptable nuisance” example is the time I asked someone to move from the left hand side of the escalator to the right when I was rushing for a train at King’s Cross station.
