Take, too, Benjamin Lee, who writes as Mr Miyagi (http://miyagi.sg). He once had a run-in with the cafe Cedele, when he realised the menu did not accurately reflect how spicy the food was.
After suffering much tongue-burn, he wrote about it on his blog.
Two days later, he got an e-mail from the chain’s operations manager who told him they had made changes to their menus.
“I told him that I was impressed,” said Lee.
