some ideas are just retarded.
they've been making retatdedly huge sandwiches in jewish delis in nyc for many years, and i just don't get it. several pounds of sliced meats between two teeny pieces of bread? give me a sliced loaf with it, and you have a make it yourself sandwich. gee, thanks. i couldn't have done that myself at home.
like addie said, you'd be better off by just buying the deli.
