A London man who was drinking a gin and tonic and ordering food with pals at a restaurant when he got caught up in the London Bridge terror attack said he is going back to the eatery when it reopens — to pay his tab and give staff an extra tip.

Richard Angell, 33, said he has no fear of revisiting the scene, where seven were slaughtered Saturday night in a terror attack.

“I’ll be going back to the same restaurant to finish my meal, pay my bill and give them a double tip,” he said of the Arabica Bar and Kitchen in Borough Market.

Angell said the staff reacted calmly, ordered everything to be “locked down” and told customers to take cover as the chaos unfolded.

“They cared about us and our safety,” he told the Mirror.

Angell said it’s important people keep a stiff upper lip and not let terrorists stop you from partying.

“If me having a G&T in a nice bar, flirting with handsome men, upsets them — I’m going to do it more,” he said.
