Subway sucks!

Every time I go there to get a sandwich I leave and smell like shit for the rest of the day... I don't even eat there!

Being in that store for 5 min will ruin your clothes!

I am just about to go there now

Must be your Subway. I like the smell of fresh bread.

Subway improperly handles it's food.
They wear very cheap disposable gloves and those gloves go every where.
Cheap disposable gloves are known to transmit "stuff" through them and offer very little sanitary protection (this has been proven in food lab experiments).
Workers tend to wear them continuously in the mistaken belief that this will prevent both contamination and cross contamination.
This is the same thing that occurs with uneducated persons visiting a contagious patient in the hospital.
They suit up, go in to the room and keep the suit on after leaving the room infecting every living asshole they meet along the way back to their car.
The subway gloved hand acts much the same way.
If the beef is a little off, well the lettuce gets contaminated by the same bacteria by virtue of the "clean" gloved hand.
So even if you don't order beef you may get sick anyway cuz your turkey sub gots lettuce on it too.
See how it works now?
Stick with restos that use individual serving utensils, one for each and every item, it's the law in a a lot of places, you can see it in action at many all-you-can-eat self serve buffets.
The individual serving utensil is a lot cleaner and more sanitary then any gloved hand, after all you wouldn't take a piss by holding your dick between two big spoons would you?
Oh, btw enjoy your next meal!
