Other businesses across Suffolk, including Harriet’s tearooms in Bury St Edmunds have also experienced abuse.
Roger Barrow, who has run the business for 25 years, said he turned a customer away because he was about to close, and faced abuse that resulted in him having to call the police.
“I got nothing but insults thrown at me about my business,” he said.
“I found myself making apology after apology and she refused to move away from my doorway.”
Barrow said calling the police had been the last resort.
“This is a very, very small minority of customers,” he said.
“In hospitality, most business owners would agree, you remember these moments and too often we forget all the amazing experiences all our customers have had.
“It’s rare, but these stay with you for a long time.”
