Vegas relies on its service industry, and tips are essential for the employees such as the servers or waiters, valets, maids, or bell hops, that are usually paid the minimum or just over the minimum. Don’t forget to tip at least 15% when dining out or handing over a buck or two for drinks that come your way and it will surely be appreciated. However, make sure you know who to tip as store or retail clerks or pool attendants, for example, are generally not allowed to accept tips.
