Is it possible to say the following at a store?
I want to buy (a coffee/two beers/three cokes.)- not a served one, but existing products sold in market if they come out as a product.
But would you say "give me two coffees or two coffee." at Tim Horton or Starkbucks?
At a place where they serve drinks, you'd say "two coffees" or "three Cokes."
At the store, you'd buy two cans of coffee, three bottles of Coke, a six-pack of beer.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
