Greg, from Ultima VII
Greg is the owner of the tool shop in Britain. He's a man who makes up bogus stories just to impress his customers.
When the Avatar met him in Ultima VII, Greg spoke in high praises of his shop and his customers, even adding a (most likely bogus) story about Gorn, who'd bought a shovel from his shop and managed to defend himself from a group of Skeletons with said shovel.
He didn't stop there and also claimed to have moved his shop from Paws just to be close to Lord British, who he claimed bought all his equipment for expeditions (he actually hadn't left Britain in many years) in Greg's shop. Greg claimed that even the king was very pleased.
After a faux-pas, Greg reluctantly admitted that he'd met someone dressed like the Avatar—namely Sullivan—and that there were numerous people around who claimed to be the Avatar, before finally deciding to only talk about business.
