So I work at a winery. There is somewhat of a gray area regarding tipping. We aren't really bar tenders or waiters so some people (I assume) just don't know to tip? Some days are better than others but over all I'd say about half the people tip. I try not to take it personally. BUT the last 2 years I've worked Thanksgiving and received $0 in tips both times. I'm working again this year. I need a way to tell people that YES you are supposed to tip. You are supposed to tip WELL when people are working on major holidays. I'm taking time from being with my family to make sure you have a good time. Like some line I can casually drop so they will get the hint. I've even considered printing something out to give with the menu. Something like “We hope you had a great time! Please be advised that gratuity is not included in your tasting fees.” I need help coming up with the right phrasing. Thanks!
