This is the moment when "scared" curry house staff claim diners threatened to "beat them up and then hid in their car park" to avoid paying a £90 dinner tab.

Shocking footage shows a blonde female diner’s card being declined on Sunday, November 6, after she ordered four curries, eight sides and six drinks with two dark-haired men.

When she went to settle her bill at the cashpoint machine at Namji, Milton Keynes, staff allege one of her companions threatened to attack them before he fled with her.

Restaurant Owner Naseem Khan, 44, was in the kitchen when the disturbance unfolded, and when she tried to find the diners in the car park, they were nowhere to be seen.

This is the second recent incident that Naseem - dubbed the "Queen of Curry" due to her work with homeless people - has dealt with from dine and dash customers.

In October, she released footage of a woman who allegedly inserted a piece of plastic from her bra into her food before storming out without paying her family’s £170 bill.

And following the latest occasion, she said she wanted to “scream and cry” with rage.

She said: “When it happened, I was really angry. I wanted to scream and cry.

“There were customers in the restaurant. They witnessed it. I was infuriated. It was a lot of money. It’s really affected me mentally as well. I’m so angry."

Naseem, who owns two curry restaurants in Milton Keynes, Bucks., said the diners, aged in their late 20s, had come to her Xscape shopping mall site at 4 pm yesterday.

She realised there was a problem with the group after they first complained about their meal, including two tikka masalas and a Chicken Lahori Karahi, costing £92.29 in total.

She said: “They had a lot of food, but it was nothing you might not have expected.

“This time, I was in the kitchen. My manager called in and said: ‘There is a group who are complaining about the food, but they’ve eaten everything.

“I went up to them and spoke to them, but they said, ‘There’s no problem, no problem.’

“Then my manager tried to take the money from the woman on the card machine. But it was declined. While this happened, one man actually walked out. I didn’t notice this.”

Naseem said her manager took the woman up to the till, where they hoped she would pay in cash, but a male companion then made threats towards him.

She said: “The manager said, 'Could you come with me to the cash machine, maybe the machine isn’t working.' So she went out with her.

“But then the manager came back to me. He said while I was away, a man had come in and said he was going to attack him, and he was going to beat him.

“He got scared and came to get me. We then went looking in the car park for them. But they must have hidden somewhere. We did run behind them, but they disappeared."

The staff member who dealt with the couple said he had been threatened by the man after he came out from behind a pillar in the restaurant

He said: “I went with the woman to the cash point, once I got there I saw the man hiding behind a pillar and [he] came out as we approached the cash point.

“The man then shouted and said ‘Why are you following my wife?’ To which I responded, ‘I’m not following her, she hasn’t paid the bill.’

“The man then threatened [me] and said: ‘You have two options either leave or I will sort you out.’

Naseem said she was now considering whether she needed to get customers to pay upfront, adding she didn’t want to treat them all as “thieves”.

She said: “The problem is, I don’t always want to be looking at customers coming in and thinking they are thieves.

“I want to be happy. I don’t want to look at customers and think they are not going to pay.”
