I like sandwiches that someone else made much better than the ones that I make myself. To this day, I will select the ingredients, get them out, and then get my wife or mother to make it for me. I appreciate a good, clean diagonal cut as well. I am also ever on the lookout for anything that will make the bread soggy. Wilted lettuce is another big no-no and is sufficient reason to either dismantle the sandwich and rebuild, sacrifice part of it, or just throw the whole thing in the trash.
Funny, I am not a picky eater at all in most other ways but I will almost hurl looking at a case of wrapped, pre-made sandwiches. Smooshed soggy bread disgusting little bastards.
