Came across this the other day. A pastor recently moved to Connecticut and was about to officiate at his first funeral in that state. He asked the funeral home director if he could have a cup of coffee before meeting with the family and was told Connecticut law forbids food or drink except for water in funeral homes.
I found this surprising as did the pastor. After looking this up I found that this is indeed a law in that state as well as three other states: New Jersey, New York and Massachusetts. These laws went into effect in the 60's and as one story puts it, "No one is exactly sure why they were put in place."
There seems to be several food issues going on. Funeral homes providing actual food service and families bringing in some food to tide them over during long visitation hours. But neither is legal in the above states including even a cup of coffee whether from a pot at the funeral home or brought in by a family member.
