This is a bad example no doubt on the part of the immigration in Mumbai... but it does not absolve you to take any country fro granted.. try to reason with the US immigration ... say you did not bring your GC.. man if you overstay your B2 in the US .. you will not realise that the visa has been cancelled until the next time you actually land.. assume you are a 70+ senior citizen who has travelled all the way from India.. there is no lax for any thing.. It is a equal world.. the immigration could have been considerate- however it is your fault to have taken the country especially India for granted
