I’ve been guilty of it too, more’s the pity. It isn’t something I thought about until I more or less quit eating that kind of thing.
The best cure is to probably slather dip onto crackers and ignore the chips. When you think about it, it has to be way more sanitary for the hostess, presumably with clean hands, to be the only one handling the food. Think of dirty hands grabbing the chips, taking too many, some falling back into the bowl...ewwwwwwww......
Really, you can use tongs, salad servers or really large spoons/ladles for serving chips.
Oy, I used to have a friend who made what seemed like 100’s of itty bitty finger sandwiches for every event. I mean, NO one makes finger sandwiches anymore, but this woman was queen of the Pineapple & Cream Cheese wedge.
