A “well drink” means any house liquor that is conveniently located in a bartender’s well. A call drink is where a customer requests a brand name for his or her drink. Well drinks are usually slightly cheaper than call drinks.
Both “well drink” and “call drink” have been cited in print since at least 1968.

Call – refers to a named spirit used in a drink; above the well liquor. Absolut is a typical call vodka, whereas some cheap swill like Popov would be the low-budget well vodka in the speed rack.
Well – the generic liquor used in a basic drink. If one orders a vodka collins, the well liquor will be used.
