Spice Jet Airlines — denied check-in at goa airport

I was supposed to travel through spicejet flight-sg454 from goa to mumbai. Due to a major accident on the way there was extreme congestion on the road. As a result in a flight scheduled at 13:30 we reached the check-in counter at 12:55. Just due to a delay of 10 minutes we were denied check in and were asked to book another flight. We spent time discussing our problem rather than finding a viable solution. The staff was ignorant to our problems and wasted even more time. Many more passengers were late due to this but no solution could be found. Reluctantly we found another indigo ticket. The irony is on the very same day, another spicejet flight from goa to hyderabad was delayed by 1 hour and 45 minutes! It is an irony that a circumstantial delay of 10 minutes by a passenger is unacceptable while a delay of 1 hour and 45 minutes by a large corporation causing inconvenience to many is totally fine.
