He said that, while preparing to open his shop at 7.30am each morning, he had seen people outside urinating into a street bin, fighting and other drunken behaviour including people throwing rubbish around the city centre streets.

He said: “It’s depressing to see it.
“It’s like the Wild West don’t want to be seeing it. It upsets my staff to see it too.
