Quite bizarrely I was on Candolim beach last Easter on Good Friday and the beach was packed.....but most of the shacks were closed for the day!!!
Given that Christians (mainly Catholic) are the second largest religious group in Goa, bizarre though it might seem to people in the UK, could it be that this was done out of respect for the most solemn day in the Christian calendar - one which is a fast day in many countries still? I don't regard myself as being that old but even I remember when it was standard practice for shops and restaurants to close on Good Friday in the UK too. Yes, non-religious families welcomed it as an opportunity for a family day out or a long weekend but it never used to be a case of 'business as usual', even if only a minority attended Mass or the vigil services.
