People just discovering how meal deal sandwiches are made vow they'll 'never eat them again'

Meal deals are arguably a staple part of British working culture; however one video seems to have destroyed customers' relationship with the convenience food for good.

Easily accessible with plenty of choice (depending on the shop you visit) and available for a reasonable price means that Brits up and down the country regularly rely on their pre-packaged sandwich, crisps and drink to get them through the day.

But have you ever spared a moment to consider how these sandwiches are made?

Of course our sandwiches, wraps and pasta pots don't just appear out of thin air readily made, they're the end product of mass production at your local sandwich factory.

And a video taken from inside one particular sandwich factory has left viewers horrified.

Take a look at the clip for yourself below:

The clip is taken from an episode of Discovery Channel's long-running series How it's Made back in 2001 and shows blocks of bread being checked over by workers before being loaded en masse into a machine.

The machine then adds a spread of butter to each slice before mayonnaise is squirted onto each slice in a rather disturbing manner.

From this point the bread slices make their way down the conveyer-belt and towards the employees who are waiting to add fillings such as meat and cheese before closing the sandwich and passing it through a machine to turn them into perfectly shaped triangles.

And that my friend, is how your meal deal favourites such as cheese and ham or chicken and stuffing are made.

Now there are a few important caveats here. How It's Made doesn't mention a specific factory in the segment or which supermarkets the sandwiches end up in, which means your favourite lunch staples could be made differently.

The segment also shows an example of a sandwich which is made entirely via a robot, featuring equally disturbing blobs of egg mayonnaise mixture.

However anyone who regularly goes for an egg mayo sandwich needs to re-evaluate their life priorities anyway.

Viewers were of course horrified to see the way their lunch was being handled in the clip. "I think the machines putting the sandwiches together are cleaner than them hands," one person wrote, while a second added: "Bruh, those bare hands grabbing the ham, spreading the cheese, pressing on the bread..."

"Bare hands? No hygienic food safety gloves? No thank you," a third added.

However others were able to see the funny side of the situation, as one disgruntled sandwich muncher joked: "That dude who spreads out the handful of cheese must have had the day off when my sandwich was made."
