Would it look really weird/awkward/desparate/insert negative thing here if I said something along the lines of:
Me: "where do you go for lunch"
Other Person(OP): "Oh I go to the field"
Me: "Any chance I can join you for lunch?"
Me: "Great, where should I meet you?"
Obviously that wouldn't be word for word because you can't really plan it like that but just something along those lines?
