Just as in other U.S. destinations, workers in Las Vegas are paid a minimal wage and rely on tips to make up the primary part of their income. A $1 tip per drink is appropriate for cocktail waitresses, even when they bring you a free drink at a slot machine or casino table. On package tours, conductors and drivers usually get $10 per day from the group as a whole; check whether this has already been figured into your cost. For local sightseeing tours, you may individually tip the driver-guide $5 if he or she has been helpful or informative. Tip dealers with the equivalent of your average bet once or twice an hour if you're winning; slot-machine change personnel and keno runners are accustomed to a buck or two. Ushers in showrooms may be able to get you better seats for performances for a gratuity of $5 or more. Tip the concierge 10%–20% of the cost of a ticket to a hot show. Tip $5–$10 for making dinner reservations or arrangements for other attractions.
