Waheguru Ji Ka Khalsa Waheguru Ji Ki Fateh Ji
i also attended the week long Vaisakhi celebrations at Dasmesh Darbar. As you know, due to the arrival of the amusement rides in the parking lot and due to the construction of the new building, there are alot of construction workers are carnival ppl around. The cigarette must have been theirs.
Think about it, even a Punjabi person who is not into Sikhi would not dare smoke a cigarette in the Gurdwara Sahib complex. If anybody saw him he would be insulted and probably beaten up. So, its likely the cigarette belonged to either a construction worker or one of the carnival ppl there.
