The way your describing it now, BIG DEAL.
They dont see teffiln every day and possibly some kiruv rechokim might help.
In Egypt my tiffin was opened, I explained diligently what it is, its holy and needs to be respected, they respected it.
Imagine someone walking thru an airport with these boxes wrapped in belts while your the security officer.
If they disrespected him, threw down his items or damaged it, it would be a different story and in such a case action is required.
