Happy Hour is the classic example of "dynamic pricing" being marketed correctly in hospitality. It's been used at restaurants, bars, strip clubs, hell I've even seen fast food places do it before. Taco Bell used to have a late night menu with discounted options. I've seen it at I think Steak & Shake or Habit Burger or one of those smaller chains too. In an economic sense, price discrimination is an effective tool. Particularly for goods with high fixed costs. Hotels and Airlines have been doing it for years. I think Wendy's mistake here was in marketing it, what they released was more suitable to shareholders than customers. The customer facing release should have started with something similar to the happy hour concept, with discounts between 2-4pm and/or 11pm-1am or similar times. Then they could quietly tooled up their signage and moved to the end state surge pricing model with much less bad publicity.
As far as strippers and strip clubs go, absa-fucking-lutlely they do. Every club I've been to has day/night prices. Cover charges are another example, they're always higher during popular times. Even the girls, in and out of the club, prices are much lower for off peak times. If I ask a girl to see me OTC on a Sat night, she's gonna want a lot more than on a Tue night. I don't know how anyone who has been to a strip club more than a few times hasn't experienced this first hand.
