I went to a friend's house last weekend for a BBQ and it was the strangest set upnjbe ever known.
You had to let host know what you wanted cooked for you... So you had to say "1 burger, 3 skewers" that kind of thing
They cooked exactly and only what was ordered and have it to you on a plate.
Never ever seen this before! I know it's not normal... Bit so bizarre!
