Is BBQ Sauce On A Meat Pie Treason?

Nige had a big night with a friend and he is a little hungover today. One of the questions Producer Billy asked was what snacks Nige had to enjoy himself. One of Nige's favourite snacks is little meat pies. Billy wanted to know what sauce Nige used.... to which he said 'TOMATO!'. Billy said what about BBQ? Nige was in shock. It is definitely a rule (not one that Nige made up but one that he is believes is real) that BBQ sauce does not belong on a pie or even a sausage roll.
