Drive-Thru Liquor Stores

One thing I've often wondered is why they don't have drive-thru liquor stores. Most people entering a liquor store want liquor on the go. Plus it would save a lot of embarrassment for a lot of people. Like, you're just gonna end up in a quiet parking lot drinking it and listening to the radio anyway, just like you do with fast food. I always prefer listening to the radio when I'm in a quiet parking lot cause the radio hosts make me feel like I'm with friends. But never when I'm driving. That's just annoying.
