The Florida diner where the owner posted a sign turning away Joe Biden voters after 13 US troops were killed in Afghanistan has had to shut its doors - because so many people called to buy meals for veterans that the small business ran out of food. 

'I've gotten so many people calling me from all over the world, from Europe, trying to purchase meals for veterans, which I still haven't been able to organize,' said Angie Ugarte, who posted the sign in the window of the DeBary Diner in the central Florida city of DeBary.

'I think that the veterans will be fed for the rest of the year at the rate I'm getting donations.' 

The sign told customers: 'If you voted for and continue to support and stand behind the worthless, inept and corrupt administration currently inhabiting the White House that is complicit in the death of our servicemen and women in Afghanistan, please take your business elsewhere,' the sign read. 

 The business was temporarily closed Thursday due to the overwhelming amount of donations and diners the day before.

'Hallelujah!' a patron said upon noticing the diner had sold out of food following Wednesday's rush of support.

That didn't stop supporters from stopping by on Thursday, with one woman posing in front of the diner holding a Trump 2020 banner, while others coming from Daytona Beach, Hunter's Creek near Kissimmee, and Monticello just east of Tallahassee.
