Standard buffets aren't really an issue for me... I'm not a fan of pastry, so I tend to stay away from pasties and pies, not a huge fan of sausage rolls either, and even sandwiches aren't majorly high on my list, might have a cheese or ham one, but I hate egg. I usually find myself reaching for the chicken drumsticks or salad-y type things.
Although if they've got cocktail sausages, or cheese on cocktail sticks with pineapple or something, that's me done... flipping love them!
