"Be careful what you wish for, you just might get it" is an expression that has been around for a long time, with one source saying it might date back to use in a story in 1902 by A. Nonymous.
Many people (and politicians) in our commonwealth are wishing the Pennsylvania Liquor Control Board would get out of the retail liquor sales business, hoping private sellers would continue to provide the half-billion dollars a year the PLCB generates for state coffers. They believe if the PLCB would just go away there would be better service, more selection and lower prices.
Based on my experience travelling around the United States and living in a number of different jurisdictions, it won't happen. One or two stores in a geographic area might offer just that. Most won't.
Most of the liquor stores I have seen offer only the most popular items. They don't carry the less popular ones. The prices in most stores other than a few discount stores are not the lowest possible but are whatever traffic will bear.
The people behind the counter, and generally it is service from behind a counter, are not the most informative and don't know anything other than "a lot of people buy it."
Then there is the problem of liquor store robberies. With only one or two clerks in a store doing a large cash business, they are prime targets for crime.
As I said, "Be careful what you wish for, you just might get it"
