I guess you lads are put off by sloppy seconds.
Perhaps they should have different prices depending upon the time of day and how much action the girl has seen.
Fresh product which is on offer at 11:00 should go for full price, and then the price falls as they have more custom throughout the day and presumably they are tired and will not give the same level of service.
The grocery store near my house sells suchi in a package. If you get it for lunch the price is something like 10 pieces for $48. Same package at 8:00 pm (which I usually pickup for dinner on my way home when my wife is traveling on business) is $40. If I roll up to the store at 10:00 when they will be closing, and the package is no longer "fresh" it can be had for $25.
If I was a girl this is how I would do it. Prices are a signal to the buyer (read Adam Smith). Low prices relative to the market price tell the buyer that he should not expect the best in quality, service, freshness or whatever.
Just my 2 cents
Keep on mongering
