Bad service

I was told that we were not allowed to order the brandy special at the restaurant section and only in the bar, but I can order at the bar and take it to the restaurant, upon drinking one glass at the bar and taking the second glass to rejoin my family at the restuarant I was aggressively told what am I doing I an not allowed instead of being told politely after a waiter said I can do this... The is very degrading as a loyal patron coming gere for more than a few years.
