Villas - I am sick and tired of eating in local restaurants, and large groups come in and think they're the only ones in the place. With no respect for others eating there. Yelling, screaming, talking loudly on cell phones, running around taking selfies, etc. The manager, or owner of the place does nothing, and lets this go on knowing other customers are upset. Just to get their money. Don't you think you're going to lose customers, locals who live here year-round because you don't want to ask those groups to keep it down?
