Customers of Guys and Dolls are sternly advised to "Please sit up straight, uncross your legs, keep your feet off the furniture, and please don't smoke while your hair is being cut." The sign on the wall is no joke, says co-owner Linda Lafrato; at the height of the season, her colorful beachfront salon draws weird walk-ins like driftwood. Maybe it's the huge row of red, green, orange, and purple "passion flowers" painted along the outside façade or possibly the six-foot, hand-carved teak "Java Man" statue waiting just inside the front door to greet unsuspecting visitors. Or maybe it's just they've heard this is an always-reliable spot to have your hair cut, curled, styled, teased, shampooed, combed, and blown dry for a reasonable price by a friendly and talented crew. They heard right.
