Burger King in Norwich is to put up new signage after complaints of littering and a lack of seating.
It comes after workers in neighbouring shops in Brigg Street complained people were littering close to their stores, as burger lovers had no choice but to take their food outside due to a lack of indoor seating.
But the fast food restaurant says it has no plans to add additional seating as the branch, which opened in April 2022, is designed to "offer local residents a place to grab our menu on the go".
One woman in a nearby shop, who did not wish to be named, said she welcomed the restaurant but had become concerned after seeing its customers littering the street and using other businesses' tables.
She said: "It's good to have more food places like this in the city where people can have something to eat quickly and affordably, but there's literally four seats.
"We've seen people using the tables in Pret to eat their burgers and as people get pushed into the street to eat they naturally drop food as they eat.
"They could easily get some more tables in there by having a move around, they never had this issue when they were in the Castle Mall.
"It's not good for their business either, I've gone to McDonald's instead when those seats inside have been taken."
Following the complaints, Burger King confirmed it would be putting up signs telling people to bin their rubbish.
A spokesman said: "We are committed to tackling litter and therefore conduct regular litter-picks both immediately outside our restaurant and also in the area close by.
"We will also be adding clear anti-littering signage at the restaurant to help reduce this further."
It comes after police announced they would be increasing patrols in the area following reports of anti-social behaviour including littering outside the Haymarket McDonald's.
