I'm from India and I visited Tokyo recently. This was my first foreign trip. At Haneda International Airport I bought a few items and tax was exempted for foreign buyers when I showed my passport but they attached the bill and a slip in my passport.
What should I do with that bill now? Can I remove it or should it be in my passport forever? I thought when I reach India, Customs people would check and remove it but there was no customs check.
So, what do I do with it now?
