We use little plastic tubes the same way. But even though my wife is a professional chef, we don't take a big selection of spices. WE do dehydrate our own food a lot, so maybe we feel that it is already seasoned. But even when we take "store-bought" dinners, we just take salt, pepper, some chili oil, lemon juice, soy sauce. All of these come in individual packets at the deli.

And we probably use the salt and lemon juice the most.
