Gerald/Baz
He saw that Basil was already hard at work checking the inventory. Though he could have asked the girl working the booth, but that didn't seem to occur to Basil. Always his own way.
Gerald arched an eyebrow and grinned more at Basil's reaction to the shirt. "I bet you that most of the people you ask around here, won't even know what the word gauche means. Besides, if you don't want one of the band shirts, get a Stonehenge one," Gerald said. He looked at the perky intern again and Gerald asked her. "That won't be a problem, sir!" she said. Ugh, that made Gerald feel old, even if the girl was trying to get his attention.
"What do you think?" he asked the girl, grabbing another shirt, and holding it up in front of Basil's chest so she could see. "Look good?" Gerald said looking for her opinion. "Oh yes, I think he'd look mighty fetching."
"There you go Baz. No harm from wearing it then," Gerald said. "You can look like a rocker today, and go back to being a sharp dresser tomorrow," he said. He was more amused than anything, trying to get Basil into a t-shirt. Gerald thought the other man actually dressed fine, he was just worried about him, that's all.
