The danger range temperature wise for food is between 40 and 140 degrees F, this is where bacteria grows at exponential rates. Personally I have consumed similar food left at room temperature up to four hours later, I wouldn't recommend it, but it didn't "kill" me. I personally wouldn't eat any similar food left in 90 degree summer heat after four hours but I seriously doubt its going to kill you, at worst it may make you sick.
A bacon, lettuce, and tomato sandwich is usually served while the bacon and toast are still warm. The mayonnaise, lettuce and tomato are cold.
To get mayonnaise out of a leather purse, you try washing the mayonnaise out with a cotton cloth with warm water and no soap. Let the purse air dry after
I like egg sandwiches because they are very tasty. I eat them hot; and they are warm and filling. I like the eggs fried, salted and peppered and on white bread, sometimes toasted, with mayonnaise and onions. They are also delicious with sliced tomatoes and lettuce on them.
Because all the items in a BLT are not warm items. therefore, they are cold
Drinking warm soda will not kill you.
How warm?
Open faced sandwiches are always a fun idea for a new kind of sandwich. Turkey, rye, and advacado are all good options for a cold sandwich.
Like a panini sandwich, when it is pressed the cheese melts and the sandwich is warm. The sandwich is easier to eat because not everything is falling out the side.
Aluminum foil would keep a sandwich warm longer than a foam box. Not sure I would agree with the foregoing: aluminum is a very good conductor of heat and gains (or loses) heat easily. Foam would insullate the sandwich better, minimizing any temperature changes, and therefore would keep it warm (or cold) longer. See the link below for more information

warm water because it kill the bacterias.
