This is the way Mumbai ke TTE check tickets, personally seen at Thane, during morning hours, those who have a have a bag and those who walk in hurry, unko TTE kabhi nahin puchte ticket.. Unko malum hai yeh daily passenger hai, season ticket wale, office jaane ke rush mein.. Those who walk without a bag and who walk in no hurry mode, unko pehle ticket puchte hai..
Experienced many times the day I have bag and have college ID on my neck, TTE does not ask for ticket, the day I walk without any bag in time pass mood that day each and every TTE asks for tickets..
