Good thing owner Jean-Philippe of the Jean-Philippe Salon is so good-humored and patient. Otherwise he might be ready to kill something today, 10 days after a third-floor toilet at The Pavilion shopping center on Lovers Lane overflowed and flooded his first-floor salon there. After closing for a day a week ago Monday, the Belgian-born haircutter is back in business–sort of. Much of his ceiling’s ripped out, rendering a third of the shop unusable, and gargantuan fans continue to roar all night, trying to dry the place out. Meantime the Pavilion management is promising all will be fixed soon, and Jean-Philippe hasn’t lost his humor. “I was baptized–and flushed,” he says with a grin. “But luckily they didn’t s*** on us.”
