A double glazing salesman launched a violent assault on a customer moments after discovering they had spoken to a rival company, a court was told yesterday.
Carl Birkenshaw, 42, allegedly threw a series of punches at George Dixon after accusing him and his wife of wasting his time during a meeting at the couple’s home.
He erupted with rage when Mr Dixon informed him that they had already sought a quote from another firm for new windows to be fitted into their luxury conservatory.
