Clients of the Shady Lady Ranch will get a $50 gas voucher if they fork out $300 - worth about one hour's worth of services - at the brothel in Beatty, Nevada, 130 miles northwest of Las Vegas.

Owner James Davis said he already has had to order another $1,000 set of gas vouchers because the first $1,000 were spent in one week.

"It's rocking along. We're doing quite well. June and July historically are not big months," said Davis, who is co-owner of the brothel along with his wife Bobbi, in a telephone interview.

The $50 rebate would roughly cover the cost of a round trip drive from Las Vegas to the ranch.

Davis said business at the ranch, which has been operating for 16 years, generally slows in the early summer. He said the brothel regularly offers specials to lure clients and his wife came up with the gas vouchers for this month.

US gasoline prices hit a record $4.08 a gallon last week, up 38 percent from a year ago.
