Setting of lather and nothing else?

The setting is probably in a war zone. If you are in an advanced english class then you will probably be asked about the setting clues. If not then you can just answer the barber shop. One setting clue is that the other character is a captain and you know that in wars there are captains, generals, etc... Also it might have been in maybe the mid 1800 to the late 1900s because of the razor and the lather. We have electric ones now and we don't use the razors because you might cut them.
