Does “drink” always mean “alcohol”?

"Drink" here refers to any alcoholic drink. But "drink" doesn't always mean an alcoholic drink. If you're at the beach on a hot day and you say to your friend, "Let's go up to the boardwalk and get a drink," you're not insinuating anything alcohol-related. Drinking alcohol in the hot sun is no fun. If you're saying "Let's go get some drink." in front of the water fountain after outdoor exercise, that is very context-specific and "drink" here doesn't mean alcoholic drink either. So it is largely context-specific and should be easily identifiable in most situations.
