My limited understanding is that for most states, if a store, even if accidentally, sells to a minor and gets caught a certain amount of times, the store will lose it's liquor license. This results in the following problems: * Underage College students and teenagers are very creative at appearing way older than they are if it means getting booze * People who are of legal age, particularly older men, will often get offended if carded since it implies the person asking thinks they are young looking Making it a policy to just check the ids of everyone decreases the amount of people offended and decreases the risk of losing your license which could destroy your business. I imagine your varying experiences across multiple states is a combination of individual business decisions and how strict that state is with enforcement.
