NikNak,
If two airplanes are shooting approaches to an uncontrolled aerodrome at opposite ends and never know of each other until they meet over the field, then someone didn't make the mandatory calls on the local frequency.
As is the norm in Canada (where I am), I would suspect that an airport deserving of an ILS or at least an instrument approach, would also have a mandatory frequency for afterhour use.
Now, on a more serious note: Do you really have your underwear drycleaned?
