Take the following as truth: Cups of tea or coffee are traditionally offered to oil the wheels of the deal although today you may be offered the ubiquitous coke instead and if you are serious about buying don't turn this down as it's a symbolic stepping-stone marking you apart from the mere browser.
Then the following statement: "People will be offended if you turn down the offer of a coke." is true, false, or inconclusive?
Answer: Inconclusive
