First of all, I don't think business owners should be told how much they have to sell their products for that they purchased, but if we are going to have these rules, they should only be when needed for public safety. If you look at recent trends on drunk driving in the state, it isn't of any particular note after 9pm. There isn't a reason to think that people, who aren't currently over indugling in alcohol, would suddenly see that it is $2 cheaper and decide to become an alcoholic. That just isn't realistic. Restaurants currenlty end happy hour at 6pm in most cases. They are trying to bring in a few extra people during slower times. These days people aren't out late anymore. This would most likely result in a few more people who get off work later coming in to have a drink or two, not in mass partying. Restaurants are likely to use it as a 9pm or 10pm to midnight way of gaining a few extra sales. We should trust the bartenders to do their job in not overserving. Trust the patrons to know there limit and act like adults. In general, allow people options when there is no reason not to.
