Tefillin and Siddur in Restroom
Sometimes I travel by airplane with a carry-on only and no checked luggage. Included in my carry-on are my tefillin and siddur. Airport regulations prohibit leaving luggage unattended or with a stranger. What is one supposed to do if they have to use the restroom at the airport, but their tefillin and siddur are in their luggage that must be kept with them and therefore brought into the restroom?
