Richard Moore outside the Twin Dynasty Chinese restaurant in Windmill Street, Gravesend. A diner says a restaurant has lost hundreds of pounds of business after it accidentally sent an abusive email to him. See MASONS story MNEMAIL. Richard Moore, 28, of Hever Court Road, Gravesend, was left stunned when a message sent from staff at Twin Dynasty popped up in his inbox after he asked about available discounts for a group of 12 people. The Chinese noodle bar and restaurant in Windmill Street, which promises fresh and affordable food in fun and friendly atmosphere, replied, explaining that no offers were available. He then received another from the same account that read What do you think of this cheeky f***er?. Staff say they have apologised for the error, described as a genuine mistake sent to the wrong recipient but Mr Moore revealed he was less than impressed by the episode. Mr Moore said his party of a dozen friends and relatives were likely to shell out as much as £400 had they booked a table at the restaurant.
