I recall one of my favorite restaurants was on the East side of Lafayette, LA, just off IH10. Modest menu, but "specialties of the house" included boiled shrimp and steamed crab sold by the pound both of which arrived in galvanized buckets. Tables, covered in newspaper, had large holes in the middle, below which sat a garbage can for shells. It was the first place I remember providing a roll of paper towels for napkins, and entrees, etc., other than shrimp and crab were served on paper plates, also consigned to the "central disposal facility". Wise patrons brought their own cracking devices, since the joint provided only hammers.
