The service industry can be a thankless one. Fortunately, IndiCard’s got your back. The app, which launched in Denver before expanding to Las Vegas and other markets in 2015, is like Groupon with special offers and discounts strictly for those who work for tips—hospitality, nightlife, entertainment and other service employees. Las Vegas’ growing network includes more than 200 businesses and 10,000 users. You can find everything from hookups at XS and half-off on your tab at Nacho Daddy to $500 off a Love Photography wedding package and 15 percent off at the Lion’s Den Adult Superstore. Hey, bartenders have their kinks, too! The app is free—they verify your employment so you can’t mooch—but like everyone else in the service industry, the creators accept tips via the app, too.
