in Toronto after being told they ran out of meatballs for a sub

A customer at a Subway restaurant in Canada completely lost her cool after being told by employees that they ran out of meatballs to make a sub.

Another customer recorded a more than three minute long video showing an unidentified woman yelling and cursing at the employees at a restaurant location in Toronto.

The woman, who was carrying a few rolls of money in coins, tells the employees that they 'should have it available all the time', in reference to the meatballs which is the prime ingredient for the 480 calorie Meatball Marinara sandwich.

'And yet somehow, you guys never have it available when somebody comes in to order something,' she says.

'But you should have it available, that's the f***ing problem. Why don't you have it available?'

It's unclear what an employee tells the woman in reply, but whatever the response was, it angered her more.

'Then make it before you f***ing get on shift. If it's actually on the menu up there, then make it off the menu,' she says while pointing at the restaurant's menu.

'Then put a sign up there that says 'it's not available'.

One employee tries to make another suggestion for her to choose a different sandwich, and she replies that 'it's not what she wants.'

'You don't understand actually, you're just trying to calm me down ... that's not what I want. It's not what I want,' she angrily tells the man.

The woman yelled: 'But you should have it available, that's the f***ing problem. Why don't you have it available?'

The upset woman continues her rant about the Meatball Marinara sub not being able to be made for before explaining how she moved into an apartment above the restaurant six years ago.

'In six years, you have done the same f***ing thing,' she yells, seemingly accusing this location of not having that specific sandwich available for that amount of time.

She then declared that she is 'the nicest person on the planet'before continuing to yell and accuse the employees of not wanting to make the meatballs for the sandwich for six years.

Other customers in the restaurant stood by and did not intervene while she yelled at the employees who tried to defend themselves against the seemingly irate woman.

'Get a f***ing meatball sub! Get it! Tell your f***ing head office to f***ing make it!' she shouted at the employees in the eatery.

'I'm not being a b****, I don't want to be an a**hole. I get your f***ing life, I get it. But that's f***ing bull****.'

She continued on to tell one of the employees who was trying to explain why they couldn't make the Meatball Marinara sub that he's not 'helpless', but 'f***ing lazy.'

It's unclear if the woman argued with the employees at the restaurant for longer than the three minutes and 39 seconds that she was caught on camera doing.
