Heat the grill to high. Wrap bread in foil and place on top grate of grill. Alternatively, place bread in the oven at 350° F while grilling the shrimp. Allow the bread to heat up for 10 minutes before grilling the shrimp.
In a small saucepan, melt the butter with salt and pepper, lemon juice, hot sauce, and Worcestershire sauce and heat through until the butter has melted and begins to simmer. Reduce heat to low.
Meanwhile, toss the shrimp with the olive oil and grill in a single layer for about 1-2 minutes per side, or until slightly charred. Don't overcook as the shrimp will continue to cook in the butter sauce. Remove the bread from the grill or oven at this time as well.
Transfer the shrimp to a large serving bowl. Pour the lemon butter sauce over the shrimp and tear off hunks of bread to serve alongside the shrimp, for dipping in the sauce.
