Like some others here, I have a "thing" about not liking to get my fingers messy and greasy, but then again, if something really should be eaten with the fingeres I go ahead anyway -- fish and chips, pizza, ribs, etc.
I remember being invited to a fellow-British-woman's home in the US and she ordered pizza -- and SHE proceeded to eat it with a knife and fork!! I didn't say anything but I thought it was ridiculous. Perhaps she had a finger phobia too, like me, but even with my phobia for greasy fingers I eat mine with my hands. Weird what people do.
