Just the other day there was a news story about the Jet Strip strip club in California donating to little league baseball. I looked up the club here on TUSCL and visited their website. I did notice the tiered lap dance pricing on their website.
Early Bird Special
$20 Topless Dances
11am to 1pm
and normal price is $30 for a topless dance any other time
Also I know Columbus Gold here in Columbus used to run a "special" of 3 songs for $99 in their VIP room before 10pm and after 10pm it was 3 songs for $150. Mileage actually went down at night because that is when they would have a bouncer patrolling the dance area. During the day they did not have a bouncer. They now just have the price set at 3 for $99 at all times.
Of course, lots of strip clubs already have a tiered structure on their cover charges or drink prices.
Also one example I know of is at Sirens in Columbus (not sure if they still do this). But their champagne rooms were half off during the day. So $150/30 minutes during the day and $300/30 minutes at night. I think their cut off time was around 6 or 7PM to get the discount. I never met any really hot dancers during the day but at night I would see several hot dancers but always convince myself it would be better to just wait for day to do the dances to save $150.
