The point of the tradition was that finger bowls were removed for that reason, over 250 years ago (likely between the '15 and the '45 rebellions; after 1746, the Jacobites gave in and accepted defeat). Anyone doing it since, was an attention-seeker or a poseur...
I've sat in a fair number of formal dinners, and I haven't ever seen a finger bowl - mainly because we use knives and forks these days...
You do remember that this is the "odd American" thread, don't you?
As they have not mastered the use of the knife and fork (except to spear and stab) the majority of the food is designed to be eaten with the fingers.
Hot Dogs, burgers, ribs, fried chicken, turkey drumsticks, pizzas, corn dogs, tacos, burritos, Po boys, club sandwiches, onion rings, bagels, corn on the cob, buffalo wings and so. All designed so they don't embarrass themselves when not knowing which fork, spoon or knife to use.
And when they do use one of these funny metal things, it's just one hand and stab the meat with the knife before transferring the fork to one hand and scooping or stabbing.
Oh, and after a dish of those "zesty" buffalo wings, you need a washing up bowl and fairy liquid to get the stuff off before it rots the skin on your fingers let alone a bloody finger bowl.
