I paid the govt fees online while submitting my application and got a date for my fingerprint and other stuff. On that date, I forgot to take a copy of the utility bill as proof of my present address. They told me to come with it, otherwise the process wouldn't proceed. I respected their rules and came out, then sat at a tea stall nearby. The shopkeeper asked about the situation. When I told him, he asked for 3000 taka. I refused, so he offered to do everything without documents for 2000. I refused again, took a rickshaw home, got the electricity bill, and returned. Paid the rickshaw puller 40 taka, completed everything, and saved 3000 taka for a 40 taka ride and a few more hours of queuing.
