akpors and the taxi driver

Akpos was in a taxi eating chocolate, when he was done eating the first pack, he took another one then a man sitting next to him said" do u know that chocolate will damage your teeth".

Akpos replied "my grandfather lived 132 years".

The man asked "was it because of eating
chocolate?"

Akpos replied "NO he was always minding his own business!"

The question is, was Akpos rude or not?
